Islabikes Beinn 26



Still the children's bike to beat, with super performance and incredible resale value

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Islabikes have been the leading 'proper' kids' bikes in the UK for many years, and all the reasons that they've been the market leaders still hold true, which makes a bike like the Beinn 26 Large an excellent investment. It's a lightweight bike with a near-perfect spec that's fun to ride, and it'll hold its value better than pretty much any consumer product I can think of. The ticket price is high, but thanks to the extraordinary resale value owning one of these bikes for several years will, in reality, cost you no more than half the retail price. Looked at like that, it's an absolute steal.

Isla Rowntree is a successful competitive cyclist – British veteran cyclocross and cross-country mountain bike champion across a number of years – and the children's bikes that she's been producing over the last decade show that racing DNA. Go to any youth racing event and you'll see a high percentage of Islabikes on the start line. But the reasons that they're great for racing – light weight, child-specific spec – also make them great all-rounders.

The Beinn 26 Large is a 26in-wheeled flat bar bike that's suitable for kids of about 10 and up. The wheels may be adult sized but the bike is not. The geometry of the alloy frame and chromoly fork are scaled down for smaller riders and so is the other stuff: the cranks are shorter, the brake levers have a shorter reach, the wheels are a light build because children aren't as heavy as grown-ups. You get an eight-speed SRAM X4 derailleur setup with a twist-grip shifter and Islabikes' own multi-purpose tyres that are reminiscent of Kenda's Small Block Eight, with a close knobbled tread that's good for tarmac and hardpack.

The bike can be supplied fitted with a kickstand, bottle cages, mudguards and a rear rack depending on what your offspring will be using the bike for. You can also have a name decal on the top tube, and Islabikes offer a wide range of accessories (panniers, tyre options, pedals, pumps, helmets, mitts and more) for purchase with the bike. The bike-specific stuff such as mudguards and racks is worth looking at; most of the more generic kit can be had more cheaply elsewhere.

The bare-bones bike weighs in at 9.8kg. If you're used to the rarefied world of sub-7kg race bikes that might seem a lot but there are very few kids' bikes that are lighter than this. Cheaper children's bikes of this size weigh in at up to 15kg; with, say, a 40kg rider, that's a lot of bike to haul about.

Daisy (11) has been using this bike for about six months now and she loves it. She's not really interested in racing but she's very interested in rolling along the Two Tunnels greenway to Wellow trekking centre to see the horses (her first love) and get a milkshake. On the way back there's a big old hill back up to the house and this is the first bike she's managed to conquer it on thanks to the wide spread of gears. She finds the twist shifter easy to use (although I still think a Rapidfire shifter would be a better option) and the bike easy to ride.

There's not much point going into the finer minutiae of handling with a bike like this, although suffice to say they always seem to be the first over the line at local kids' cyclo-cross races. The geometry works for the size and ability of rider, and the rest of the equipment does too. The brakes are especially good, so much so that the first application of them was a bit hairy, but once Daisy was used to them they gave her plenty of confidence. The 165mm cranks (shorter than the grown-up standard 172.5mm) work well and the 32-tooth chainring with an 11-32 cassette gives a more or less perfect range of gears for younger riders.

So is it worth £419.99? It is, but you should also bear in mind that these bikes hold their value like no other bikes. Head to eBay and you'll see that they regularly change hands second hand for over £300. Certainly you can expect to get £250 for yours after a couple of years of use, and even if you keep if for two kids you'll probably get back half what you initially paid. Looked at like that, it's a no-brainer. That's an outlay of £50 or less a year for what's still among the best, if not the best, all-purpose kids' bike. Still the one to beat, even after all these years.

Just bought a 24 for my lad to celebrate him reaching the minimum height limit. Friends have 20s and 26s for their kids so this should work well for bike swaps as they all grow. Looked at everything else in the market (Frog, Pinnacle, Genesis, Wiggins, Hoy) and none had the right geometry for his size or right kit. I did wonder about twist grip vs trigger but I think on balance twist was the right way to go - having a numbered dial really helps when learning gears. For example, I can advise him what number to shift to based on what's ahead. Easy and cheap enough to swap to trigger (£15 for the shifter) if they don't get on with it - mine does complain that its a bit stiff heading down to the larger cogs.

I'd welcome a comparative review between the big brands as the Islabikes hegemony has forced everyone to raise their game. The Genesis bikes look lovely, and the Pinnacles look good on paper for a budget option.

got a 24 small and a 26 large for mine and both are loved no end.
shame on some other manufacturers - one bike we had at 16" wheels was actually
heavier than the Isla 24 !!!

3rded, I've recently lashed out the best chunk of £800 on a Beinn 20 and a 24 for my 4 and 6 yr old, they've only just learned to ride and these make it an absolute pleasure. It is a high price of entry but as long as those resale values hold up then that takes away the sting. They're beautifully put together, and whilst the twist shift isn't great for adults the boys do like to pretend they're on a motorbike. I got the kick stands from Decathlon though, £9 vs £26 for the official ones (two of).

How does your 4 year old get on with the bike? Mine can ride (did the 8 mile London Freecycle route) but he's on a 16" with no gears. On flat ground he's always spinning out the gear and I've been searching for a bike that has gears and will fit him. Most 20" are just that bit too big for him - the 16" he's on has the seat post at its lowest setting for him to ride it!

Mine are quite tall, the 4 year old is the size of most 6 year olds (115cm), and the bike is a Beinn 20 Small, and despite it being the small frame and him being tall, I still had to take the reflector off to get the seat down enough, so it might be a stretch. That said, your boy isn't going to get any shorter so it's going to fit him at some point, and probably pretty soon.

Now the only worry I have is plod pulling him over for not having a reflector.

I picked up my 5yo's much loved CUDA bike, then his mate's Islabike.
I felt ashamed of myself and sorry for my son.

As a parent of a kid who rides an Islabike I'll second this review. They totally tore up the rule book on kids bike geometry and sizing, and it's a massive improvement. Everything else seems to use the same geometry for smaller size kids bikes and it's dire - reach too short, bottom bracket and seat too high, bars even higher, and so on.

Their advice on balance bikes v (un)stabilisers is spot on too.

I'd like to see how these now stack up against the Wiggins range at Halfords.
