One big sticking point when buying your nipper their first bike is how little time it lasts before you need to buy a bigger size; fledgling British innovators Black Mountain want to make that a thing of the past, with the launch of two kids' bikes that 'grow' as your child grows.
Black Mountain's patented technologies mean that the size of the frame, method of propulsion and saddle position can all be customised. The PowerPack is a crank, chainring and pedal system that can be easily installed to turn it from a balance bike into a small pedal bike, then Black Mountain's UP:SCALE technology allows the rear triangle to be moved forward to create a longer top tube when your child grows. There's also 'IN:GEAR', the world's first gear system that can be moved up as the bike grows. 'GO:LOW' is a custom saddle and inverted seat clamp that allows the saddle to go extra low for the smallest of kiddiwinks. Both bikes come in orange, neon green, sky blue or purple colourways, and the frames are lightweight 6061 T6 aluminium.
The Pinto, priced at £329, is for kids aged 3-5 and replaces bikes that would be sized 12" and 14". It has 14" wheels with tough Kenda Small Block 8 tyres, and weighs just 5.7kg. It has a 48t chainring with the belt drive when used as a pedal-assisted bike, and Black Mountain's IN:GEAR rear sprocket is 30/25.
The SKØG is also £329, and is recommended for riders aged 5-8. It has rolls on 16” wheels and weighs 6.1kg, with a 50t chainring in its pedal bike form. The IN:GEAR system that turns the SKØG into the larger sized bike increases the gearing and frame size by about 20%.
Black Mountain aren't actually the first to make a 'growing' kids' bike; Stu (and his then four-year-old lad Charlie) reviewed the LittleBig 3-in-1 bike back in 2016 (read it here). On this bike you can flip the rear part of the frame to make a larger balance bike, then bolt on a 28t chainring (it's singlespeed at the rear) and cranks when they're ready to start pedalling. Black Mountain's main USP's are the belt drive with adjustable gearing and the UP:SCALE growing triangle in comparison with LittleBig's design.
Both the Pinto and SKØG bikes can be pre-ordered now for a May delivery - check out Black Mountain's website for more info.
After cobbling together a few hundred quid during his student days off the back of a hard winter selling hats (long story), Jack bought his first road bike at the age of 20 and has been hooked ever since. He was Staff Writer at 220 Triathlon magazine for two years before joining road.cc in 2017, and reports on all things tech as well as editing the road.cc live blog. He is also the news editor of our electric-powered sister site eBikeTips. Jack's preferred events are time trials, sportives, triathlons and pogo sticking (the latter being another long story), and on Sunday afternoons he can often be found on an M5 service station indulging in his favourite post-race meal of 20 chicken nuggets, a sausage roll, caramel shortbread and a large strawberry milkshake.
