Black Mountain Pinto and Skøg review - our first impressions

We regularly get sent kids bikes to review at Cycle Sprog, but it's unusual to receive something completely different to everything that’s come before. So as you can imagine, we were hugely excited when not one but two new bikes arrived that are very special indeed - the Black Mountain Pinto and the Skøg.

It’s the first time we’ve had the chance to review a kids bike that not only converts from a balance bike into a pedal bike, but also grows with the rider as they get taller. It's certainly an interesting concept and probably posed many engineering headaches for the designers in getting it right.

We've had the Black Mountain Pinto and Skøg bikes at Cycle Sprog HQ for a few weeks now, and this is our first impressions review which will hopefully help you decided if these bikes are for you.

Black Mountain Pinto review

The Pinto and Skøg were the brain child of engineer and dad of two, Andy Lloyd, who decided to use his skills and initiative to solve an (expensive) problem faced by many parents - that children grow so quickly they need a balance bike plus several single gear pedal bikes in a period of just a few years.

The Black Mountain bikes come delivered in balance bike mode (unless you request otherwise when ordering), with a “power pack” that you attach when your child is ready to start pedalling. Later you can increase the frame size and decrease the gear ratio to make the bike suited for a taller rider.

This all sounds fabulous in theory, but we were keen to cast a beady eye over the bikes and find out how they work.  And, let's not beat about the bush here - we were also keen to see if we thought they were worth the money. At £330 they're certainly not cheap, and we wanted to find out whether we thought we could recommend these bikes to our readers.  Please note this is our initial review before the bikes have been ridden extensively.  Now we're sending them out to two families who will use them through the various size modes and report back how they got on in a number of months time.

Black Mountain Pinto and Skøg – first impressions review

We'd seen images of the Black Mountain bikes before we'd got our hands on them, and because of their “growing” frame they looked very different in design to the 'traditional' child’s bike that people have become accustomed to. We wondered whether there would be a weight penalty due to the additional bolts and the 'growing frame', but in reality they’re actually very light.

I like the matt finish paintwork on these bikes and the contrasting decals. It’s different to the glossy paint we see on most kids bikes and certainly gives them a distinct appearance. There are four paint colours to choose from – orange, green, purple and sky blue. I’d seen the blue on the Black Mountain website and decided it was my favourite, so was really pleased when the Skøg arrived in that colour.

Skog Review - balance bike mode

The frame shape is definitely a talking point with its unusual design and fixings. The frame welds are comfortingly robust, and on first inspection everything certainly looked well thought out and put together.

All the components that adorn the frame have been sized for small riders, something Black Mountain have termed MY:SIZE (they like capitals and colons, as you’ll soon learn).

The Pinto and Skøg – what’s the difference between the bikes?

In terms of functionality of the bikes there is no difference at all between the Pinto and the Skøg – the only variations are in the sizing of the bike. The Pinto (the orange bike in this photo) has 14” wheels and is the smallest bike in the range. It’s designed to replace a balance bike, plus a 12” and a 14” wheel pedal bike, targeting a starting age of about 2.5 years.

The Skøg (the pale blue bike in this picture) is a larger 16” wheel bike and is designed for slightly older and taller kids (aged 4 and a half and over) and is intended to replace a large balance bike, plus a 14” and a 16” wheel pedal bike. You don’t actually have to use the balance bike mode, so if your child is already pedalling you can just use it to replace the two pedal bikes.

Balance bike features of the Pinto and Skøg

Two features of the balance bike mode worthy of note are the brakes and the low saddle position.

As feet are usually the main stopping mechanism for small children, many balance bikes don’t have brakes. They add cost and complexity, so those that do fit them often only feature a rear brake to allow children to start to master braking before they move onto pedals.

Black Mountain Pinto review - balance bike with two brakes
As the Pinto and Skøg need front and rear brakes for the pedal bike mode you get them thrown in as a freebie at the balance bike stage. Your child doesn’t need to use them from the outset, and it will be interesting to see if our reviewers bother with them or not. The brake levers are made by Tektro, a reputable brand, and the levers are micro adjustable that allows you to alter them to fit the size of your child’s hand.

The other unusual feature of the Pinto and Skøg in balance bike mode is the way you adjust the saddle height. Usually on a kids bike you adjust the length of a seat post using a quick release lever or a bolt just above where the seat post enters the frame (at the top of the seat tube). However, in balance bike mode on the Pinto and Skøg it’s different. The seat post sticks out from underneath the frame, and the adjustment is done at the bottom of the seat tube, using an Allen (hex) key.

Adjusting the saddle on the Black Mountain Pinto balance bike

This is to allow the saddle to drop lower than it would if the clamp was positioned at the top of the seat tube. Black Mountain are proud of this feature and have termed it GO:LOW.

This unusual way of adjusting the saddle is great to get it into a low position, but it does have a knock-on effect when your child starts to grow. GO:LOW requires the seat post to pass all the way through the seat tube to be fastened at the bottom. The photo above has it in the highest possible position, with the bottom of the seat tube hidden inside the clamp. The moment the seat post is raised above the clamp you can no longer tighten it. This isn’t a problem if your child is going to be moving up quickly onto pedals, but if your child is either very tall or struggles with their coordination then you may find yourself frustrated.

However, when I mentioned this to Black Mountain, it appears they've already thought of this, and had a few solutions for me. Firstly, the way the saddle attaches to the seat post can be altered by rotating the clamp, so you get a couple of cm additional height.

Pinto saddle - low modePinto saddle - high mode
If that doesn't give enough height, I’ve checked with Black Mountain and they say it should be OK in these cases to swap out the balance bike seat tube and replace it with the pedal bike seat tube with the crank and pedals removed. Because this seat tube has the fixing point at the top (shown on the right below) you can raise the saddle much higher.

Difference in seat tubes on the Black Mountain Pinto and Skog
Finally, if that still doesn't give enough height for your child, then Black Mountain can supply longer seat posts for you, with the following sizes available:  185mm (Pinto), 225mm (Skog), 250mm and 260mm.

Moving from balance bike to pedal bike mode on the Pinto and Skøg

When your child is old enough to start to pedal, you need to apply the “power pack” which consists of a longer seat tube (with the seat post clamp at the top and the crank at the bottom), a reinforced polymer belt drive and two pedals.  The power pack comes in a cardboard box (no plastics here!) for storing away until required.

Black Moutain Pinto review - the power pack which converts it from a balance bike into a bike with pedals

The process itself does require a certain amount of practical know-how. The manual suggests that if you are confident removing a wheel to fix a puncture then you’re probably going to be OK. If not, you need to factor in paying your local bike shop to do the adjustment for you.

As an example, this is what stage 1 and 2 in the manual state:

"First undo the seat-post clamp with the 4mm hex key, then remove the seat clamp from the Balance Bike Mode seat tube.
Using the 12mm spanner, loosen the nut on the left-hand side of the eccentric bolt and carefully remove the nut, eccentric bolt and eccentric washer from the frame. The frame will drop slightly when you do this – be careful not to trap your fingers. Keep the nut, eccentric bolt and eccentric washer in a safe place."

Now, if this fills you with dread and you’ve broken into a cold sweat, then this may not be the bike for you. If you’re thinking “Aha – that’s clever – they must be using an eccentric bolt to tighten the belt drive - can't wait to fiddle with that” then you’re going to sail through the adjustments! Most people will be somewhere in between and if you follow the instruction manual you’ll be OK.

I’d recommend you do the work whilst your Sprog isn't around, as it does take quite some time and you don’t want an inquisitive child desperate to ride the bike getting in the way. At some points having two pairs of adult hands is useful, as is having extra eyes to read the instructions whilst you do them.

Swapping the Black Mountain Pinto from balance bike to pedal bike mode

Black Mountain supply all the tools for the job, which is essentially a couple of hex keys and a bike spanner. They were sufficient for the job in hand, although keen bike mechanics will probably want to use their own. However, throughout the instructions you are told to tighten bolts to various Nm torque, which needs a torque wrench. This is another reason why this bike is likely to appeal to those parents who are happy to tinker with bikes and have the appropriate tools. You can tighten by hand, but be careful not to over tighten (as you do need to loosen again to move into the next size mode) or not tighten enough (as the bolts could become too loose and fall out).

Black Mountain Pinto and Skog review - using the tools supplied to tighten the bolts
I’m not particularly practical and Chris loves building and restoring bikes, so he did the majority of the assembly, whilst I took photos, made notes and read the manual. The only time I needed to intervene was when Chris was convinced the instructions were wrong, so I just followed them and it worked fine!!

There is a very clear instruction video available on the Black Mountain website which shows step by step what to do, but we found the booklet sufficient for Chris’s needs. I’d watched the video separately in advance, which really helped me understand what we were doing at each stage.

The most difficult part was refitting the bolts into the frame after swapping the seat tubes – a bit of wiggling the frame around was needed to make them fit.

Black Mountain Skog seat post installation

It took us just over an hour to do the conversion, but we were taking notes and photographs along the way. At the end I had a sense of achievement having adapted the bike, and I can imagine if you were doing this for your own child, rather than a review, it would be even more so.

As it does take quite a long time to make this adjustment, it is one aspect of the Pinto and Skøg that is a little bit restrictive. If you have a balance bike and buy a separate pedal bike, your child can have a play around with the pedal bike, get familiar with it, but continue to whizz around on their balance bike. If they decide pedalling is not for them you can put the pedal bike away for a while until they are ready. With the Pinto and Skøg you’re faced with having to reverse the process to revert it back to balance bike mode. Too be honest, it only took about 10 minutes to reserve the process, but you probably won't want to be doing this too often!

Powering the pedals

The Pinto and the Skøg don’t have a traditional bike chain – instead they use a polymer belt. Whilst a belt drive is fairly unusual, some motorcycle manufacturers have used them for years and the technology is proven on kids bikes with Early Rider bikes being keen advocates. A belt drive has the big advantage of being clean and low maintenance, so you don’t need to worry about rusty chains or oily clothes – a quick wash every so often is all it needs. It’s also light weight.

It’s simple to install and you adjust the tension on the belt using the fascinatingly titled “eccentric screw”, which I’ve learnt means that the axle of the screw is offset from the centre, so when you tighten it, it moves in an ellipse rather than a circle.

Moving from small bike to large bike mode

It's when your child starts to outgrow the first of the pedal bike modes that the Black Mountain bikes really come into their own, because you don’t have to go out and buy a bigger bike. You just adjust the bike and, hey presto, they’re on the next size up. If you’ve managed to do the conversion from balance bike to pedal bike mode, then the move to larger bike is much simpler and quicker, partly because you already know what you’re doing.

Black Mountain have quite rightly given this the capitals and colon honour, calling it UP:SCALE. The frame extends in size by undoing the bolts and moving them into the spare holes in the frame. It does say in the instructions “Take Your Time” and trying to get both the bolts back in was definitely the most fiddly point of the assembly. A bit of jiggling the frame around is needed, as is patience in unscrewing the long bolt at the front which seems at first not to want to come out, but does eventually if you keep on turning your allen key and wind it out. We did notice a small amount of paint flaking off the frame around the various bolts, but this isn’t visible once the bike is reassembled.

As well as growing the frame, you can also adjust the gearing to be more appropriate for a taller and stronger child. Again this is a nifty trick and aptly named IN:GEAR. It requires you to unscrew the 30 tooth gear sprocket to reveal a smaller 25 tooth one underneath.

In this mode your child should get many more months and even years out of the bike, without you having to invest in a new one.

Wheel size on the Black Mountain Pinto and Skøg

Perhaps one of the most noticeable things about the Pinto and Skøg is that they look quite big for the size of the child they are aimed at. This is because the wheels are at least one size bigger than they’d normally start out on. With the Pinto, your 2.5 year old is starting out on 14” wheels, when most balance bikes have 12” wheels (and some 10” wheels).

It's worth pointing out that on their website Black Mountain list the bikes as being two sizes (so the Pinto is listed as being a 12"-14" bike).  This DOES NOT mean you get two sets of wheels - it just refers to the fact that the bike is designed to replace these two sizes.

Black Mountain Review - Pinto growing bike

With the Skøg, the wheels are 16" (listed as being a 14"-16" bike), so your child is skipping the 14" wheel size.

Bigger wheels have many advantages, which is why lots of adults now ride 27.5” and 29” wheel mountain bikes, rather than the original 26” wheeled bikes. It’s also why Islabikes have replaced their Beinn 26 Large with a 27.5” wheel version, and Scatto are making a 700c wheeled race bike for 6 year olds. Your child should be able to go faster and further with more stability on larger wheels, although we’re going to be interested to see if there’s any trade off in handling skills for younger riders trying to manoeuvre the larger wheels.

One thing to note is that the wheels on the Black Mountain bikes are not quick release, so you need to be carrying your hex key with you to get the wheel off if you have a puncture.

Black Mountain kids bikes wheel nuts
Whilst we’re talking about the wheels it’s worth noting that they seemed to run freely on their hubs (Black Mountain branded from Quando). The tyres are the standard Kenda Small Block 8’s which you find on the majority of quality kids bikes. They’re great for all sorts of surfaces, so your child will be fine on tarmac, grass and gravel.

Sizing and weights of the Pinto and Skøg bikes

We've taken some measurements ourselves, and they do tally with what's on the Black Mountain website, which is comforting.

Pinto Skøg
Balance Bike Mode
Lowest saddle position 425 mm 475 mm
Highest saddle position 470 mm 535 mm
Weight 4.85 kg 5.19 kg
Pedal bike mode
Lowest Saddle position 440 mm 486 mm
Highest saddle position 540 mm 615 mm
Weight (with pedals) 5.85 kg 6.19 kg
PRICE £329.99 £329.99


Weight wise, when in pedal bike mode the bikes are very competitive with the other major players in the quality kids bike market.  The balance bikes are slightly heavier than the very lightest balance bikes, as they come with brakes, growing frame mechanism and larger wheels, but they are still very lightweight.

It's worth commenting that sizing wise these bikes do come up on the slightly large side (unlike some kids bikes which woefully underestimate the height / age of children these days).  The age guide is just that - a guide - so do make sure you measure your child carefully. There is a useful measuring tool on the Black Mountain website, which will help direct you to the correct sized bike for your child.

My first attempt at finding a reviewer for the larger Skøg failed, because our reviewer was far too small for the bike. She's 4 years and 4 months (the guidance says from 4 years 6 months) but was several cm off being able to get her feet on the ground with the saddle in the lowest position.

The minimum size for the Pinto means this isn't a balance bike for a very young child, or for a 2.5 year old with short legs.

Visual appeal of the Black Mountain bikes

We've shown the bikes to a few people, and their first reaction has always been that they look very different.  As with many new ideas they do polarize option, with some adults loving them and others taking an instant dislike.

Having had the bikes around the house for a few weeks I've got used to how they look quite quickly.  What seemed a bit quirky now seems normal. We've found that children tend to be more receptive than adults to the bikes, and we couldn't get a 7 year old visitor off the Skøg in balance bike mode (even though she usually rides a 20" wheel pedal bike with gears!)

Carrying the Pinto and Skøg

One thing I found when trying to carry the bikes to a suitable place to photograph them was that the frame shape makes it difficult to pick the bikes up by the top tube as there wasn’t room for my hand. It was OK carrying them by the saddle, but the bikes lack a nice little handle you get on the back of some balance bike saddles.

This isn’t too much of a problem if your child is going to be riding everywhere, but it might be worth getting some kind of balance bike strap to help carrying it if you’ve got weak fingers or end up having to carry long or steep distances when your Sprog decides that they’ve had enough.

Maintenance of the Pinto and Skøg

There’s plus’s and minus’s in terms of the maintenance of these bikes. The rubber belt drive means that you don’t need to worry about lubing chains to avoid rust. However, this is partly offset by the need to keep an eye on the bolts in the growing frame, which you don’t usually get on kids bikes. Every so often you just need to check these are still tightened properly. It’s only a job of a few seconds but is important to do, along with the normal checks on brakes, tyre pressure etc. There’s a handy check list in the manual to remind you which checks to do and at what frequency.

Quality of the Black Mountain Pinto and Skøg

If you're paying £330 for a bike, you expect it to be well made, and we were impressed with the quality of the construction of these bikes.  The two we were sent are demo bikes, so have had the frames adjusted between the different modes more times that you'd expect under normal usage.  Apart from a tiny bit of flaked paint underneath the bolts (which doesn't show once the bolt is replaced), the only other sign of wear we could find was with the brake noodles. When taking the front wheel out of the Pinto, we noticed that the noodle had started to separate, thereby making it difficult for someone remove it from the noodle holder when trying to open up the brake calipers.  Chris did a quick test to make sure it’s not being caused by catching on the downtube, but this isn't the case, so we suspect this has been caused by the number of times the wheel has been removed and replaced during demonstrations.

Are the Black Mountain Pinto and Skøg worth the investment?

This is the million dollar question - or rather the £330 question, which is how much these bikes cost. Yes, it’s quite an investment compared with other kids bikes up front, especially when being used as a balance bike. But when you start thinking about the longer term costs of having to buy various sized bikes it begins to look a lot more attractive. From an environmental viewpoint there’s also big savings, as you’re limiting the amount of raw materials used in production and reducing the waste caused when the bike comes to the end of its natural life.

It’s worth thinking about sizing and what you’d be saving compared to buying individual bikes. With the Pinto, this has 14” wheels and is designed to replace a balance bike, plus a 12” and 14” wheel pedal bike.

In reality most people go from a balance bike to a 14” wheeler – the Pinto gives you the benefit of being able to fit pedals to a smaller bike so your child can start pedalling earlier. The combined cost of a Frog balance bike and 14” wheel bike is £375. With Islabikes it’s £460.

Black Mountain Skog review

The larger Skøg is replacing a 14” and 16” wheel bike – Frog’s offerings come in at a combined total of £520 and Islabikes at £580. That's assuming your child doesn't use the balance bike mode. Obviously savings are greater if it means you don't have to buy a larger 14" wheel balance bike too.

However…… there is a BUT with this. If you have two children close enough in age to both want to be using the bike at the same time, you’re going to struggle. You’ll miss the benefits of being able to pass down the balance bike to the younger child, because the older one is still using it in pedal mode. You may find yourself having to buy a second bike anyway.

Resale value of Black Mountain bikes

As the Pinto and Skøg are so new and will be getting used for longer timescales than a traditional kids bike, it is hard to know what’s going to happen to resale values on the second hand market. However, one thing to note is that the 3 year warranty is “transferable” meaning that if you sell the bike on within the first 3 years (or buy one second hand) the warranty is valid for the new owner.

The longer term resale values will depend on how robust the bikes prove to be. Both Frog Bikes and Islabikes have excellent resale values, and come with a 5 year frame and forks warranty. These bikes have been around long enough to prove their durability and are now well known for generally lasting well beyond this. With Black Mountain the new UP:SCALE growing frame technology means there’s an added variable to consider. However, I have been very impressed with the way the company are taking on feedback, so if you did encounter any problems I'd recommend making immediate contact with them so they can sort things out.

It’s worth saying the frames look very robust and have been tested strenuously by adult riders, so they’re obviously aiming to make a bike that lasts a long time, but time will ultimately be the judge of this.

Who would suit the Pinto and Skøg bikes?

The Black Mountain Pinto and Skøg certainly catch the eye, and I think they’re going to appeal to various groups of people:

• those who get a buzz from being the first to have something new and ground breaking
• those who love tinkering with their bikes, and relish the thought of a bike frame that grows
• those with no time or interest to keep on researching and buying new or second hand bikes, but who are happy to do two sets of adjustments as their child grows
• those concerned about their environmental footprint and want to limit purchases (although you could argue buying second hand is a better option)
• those who like supporting new and innovative British brands

If you are scared witless by even the most basic of bike maintenance then these bikes probably aren’t for you, unless you’re happy to pay your local bike shop to do the upgrades for you.  Those with two or more children close in age also need to consider whether they'll need to double up on purchases, at which point these bikes stop being quite so cost effective.

Where to buy the Black Mountain Pinto and Skøg

At the current time you can only buy the Pinto and Skøg direct from Black Mountain. If you’re passing their HQ in the Welsh Black Mountains you can arrange to call in for a test ride or to pick up your bike too.

Both the Pinto and Skøg cost £329.99 with a £10 standard UK delivery charge. Other charges apply for EU, World Wide, specified and next day delivery dates.
