You can’t escape it. Christmas is rapidly approaching and maybe you’re thinking of buying a new bike for someone, or maybe even buying one for yourself to keep those New Year’s Resolutions. A “mountain style” bike you assemble yourself can be had from many supermarket and high street retailers for less than £100. Bargain or a false economy? BBC’s Watchdog investigated recently.
Revisiting a similar item from the 1990‘s, flat pack bikes from Tesco, Halfords, Toys R Us, Argos, and Asda were tested by having ordinary members of the public assemble them using only the tools and instructions provided in the box. The retailers would have you believe that building these bikes is so easy anyone can do it and the result will be a safe, high quality machine that will give you years of cycling pleasure. But if things are that rosy, why do cycling experts warn against buying these bikes, referring to them using the derogatory “bicycle shaped objects”?
Watch the video on the BBC Watchdog site and read the comments. You should also check out the reaction from the Bicycle Shaped Object bloggers.
Taking everything into consideration it seems that two main problems exist.
Firstly, it takes some skill and experience to be able to assemble a bike properly. All the test subjects in the Watchdog programme made basic mistakes that rendered their bikes either unsafe or downright unrideable. Problems with brake and gear calibration were most common (to be fair, this is tricky even when you do know what you’re doing) but more fundamental mistakes such as not tightening axle nuts properly were being made. It seems that the average member of the public doesn’t know how to use a spanner, but as this is the target market for these bikes the skillset (or lack of) needs to be taken into consideration.
Secondly, the bikes themselves are made to extremely tight budgets and therefore feature the lowest-of-the-low end parts that often don’t quite fit or work together properly, or don’t last very long and fail suddenly when they do work out of the box. Commenters report snapping chains, failing cranks and suspension arms that break folding the bike in two, as well as the resulting hospitalisations. Do you want that happening to you?
Another consideration is that, even if built expertly and remaining unbroken, these bikes are not fun to ride and are likely to give you an unfairly bad experience of cycling. They’re heavy, they don’t steer well, the gears don’t work smoothly and they stop poorly. They’re also likely to require constant attention to keep them rideable. Doesn’t sound like fun to me.
If you’re thinking of buying a sub-£100 bike for Christmas, take a few minutes to watch the video and read the comments. Then take a few more minutes to think about what you saw.
If you’ve never built a bike before, are you absolutely confident you’re capable of doing it properly? Confident enough to ride it into traffic? Or let your child ride it? If you have the confidence, can you trust a bike made so cheaply? A bike made for less than 30% of the price most cycle experts would call “entry level”? A bike that is likely to require constant attention to keep it even barely rideable? And don’t forget the fun factor, or lack of it.
A bike can be an amazingly useful tool and amazingly good fun. If you can, push the budget boat out a bit and your investment will be well rewarded.
Otherwise, be careful.



I bought a £35 bike from Argos for my daughter and that was an absolute nightmare to put together – never again!
I’d rather buy a 2nd hand unicycle with a popped tyre than a BSO from one of those companies!
A timely warning thanks. I’d spotted the Tesco’s half-price kids bikes, thinking they just needed the handlebars put on or so (being an expert with the Toys’R'Us scooter assembly) but will view them a bit differently now.
To be fair, the programme concentrated only on adult bikes so I can’t comment on the quality of any kid-sized rides. But the cautionary notes about assembly still stand!
12 years ago when i was just a young pup my parents bought an ‘entry level’ bike @ about £100 for a downhill event cannot remember the actual brand but lets just say it was a decent one, dual suspension and even front suspension was only coming in on high end models, I had to install v brakes myself onto this model, anyway long story made short, I entered a downhill event in the Republic of Ireland and in the second day of the event, whilst coming round a particularly fast section in the course I hit a mound too hard and the frame of the bike buckled throwing me off slap bang into a tree.
This lead to 1 week in hospital bed paralysed from the neck down, not knowing if I would walk again due to the swelling around my spine, safe to say i was fine after the swelling released the pressure but from there on in I stuck well above entry level for competing and even for pleasure. A recent trip to centreparcs in Cumbria scared me as kids as young as I had been were flying down hills and off road tracks in cheap self assembled dual suspension bikes fit for road use, not as the users thought, for off road pursuits.
Go to specialist stores and if you do buy one of these supermarket bikes, at least take it to a professional cycle shop (not halfords) and have it calibrated by someone who knows what their doing.
Thanks for sharing your story Alan – I hope it makes some parents think twice about what they’re buying.
I’ve no problem with cheap bikes so long as they are safe and the purposes for which they are suitable are made clear. It’s deliberately confusing and, as you found, dangerous to refer to a bike as “mountain style” when the last thing you should do with it is take it off-road.
My sister has a cheap Townsend bike, which would have cost her maybe £70 – £80.
Shes had the bike 10 years, and whilst it doesnt get that much use, its more than capable of the sort of leisurly sunday morning towpath type riding she does.
In 10 years its needed the odd tune up, brake pads and tyres.
Horses for courses IMO
I do agree you get what you pay for but if you only do a few leisurly rides in a month some of the cheaper branded bikes are up to the task, its maybe just a minefield choosing between the competant and the dire in this segment of the market
