Great Bike if you don't want to turn corners

Lightweight, fast,

Gear movement could be smoother, poor design

used for 1 week or less Aesthetically pleasing, very lightweight and fantastic to find carbon forks at this price.
Great ride on a flat straight surface, take this bike round a corner and you're in trouble.
This bike is so poorly designed it's not actually fit for purpose.
Sadly, that's the only complaint - other than that its perfect.
I almost came off the bike going round my first corner due to my toes hitting the wheel. A few corners later amazingly it was the toe clips that hit the wheel!
I spoke to the chap in the store to see if there was a solution and amazingly he said there was nothing they could do about it. To be fair to the chap, he was very polite and immediately offered a refund but here's the quandary...I really like the bike, it performs great apart from this obvious design flaw which makes it dangerous and now that I think of potentially deadly - imagine cycling along a busy road, take a corner at speed, your foot gets caught and next your splashed across the morning papers - cyclist dead.
What really amazed me is that the chap in store suggested that all 'road bikes' are designed to go in a straight line and his bike does the same thing. His answer to the problem should I wish to keep it (and again I must remind you, he did offer a full refund) was to purchase cleats.
Such a shame that this bike which gets amazing reviews can do the simplest of tasks - turn.
Very dissatisfied and now considering my options.

Response of the brand

Dear Sir,
Thank you for your comments regarding your toe touching the front wheel when turning tightly at slow speeds. It is called toe overlap.
You may be surprised to hear that this is not uncommon with road bikes in particular if you don't use cleats.  You can find many articles about this on the web.
For you to turn the handlebars enough to catch your outer foot at speed is impossible as your speed will not allow you to turn sharp enough. If you are turning at speed your body lean should also mean that in the case of turning left, your right leg should be fully extended and your left knee raised to avoid catching your pedals on the ground/toe in wheel, legs at 6 and 12 o clock if you like (and vice versa if you turn right).  You will potentially only encounter overlap on slow tight turns.  Make sure you don't ride with your feet too far forward and keep the ball of your foot directly above the pedal axle which will also give you much more efficient pedaling action.  If you feel your feet moving forward your saddle may also be a little low.  See if this is the case.
I hope this helps put your mind at ease and with some practice and technique modifications, you will hopefully really begin to enjoy this bike.

B'Twin 500 Flat Bar

Light, Value for Money, Easy to ride, Looks Great



  (United Kingdom)

used for 2 to 8 weeks I have started riding again after a 15 year break and wanted to get a road bike for a casual user. shopped around but this was the best for my budget and so glad i bought it. The guys at Decathlon set the bike up and recommended the frame size. In my opinion as a 45 year old man this bike is light and all the components work well together. I feel this bike would be good for beginners to semi serious riders. I did commute in my younger years and i wish i had this bike when i did as the journey time would have been cut down. I have bought a adjustable stem for the handle bar as its more comfortable and with my £5 voucher which Decathlon gave me it ended up being a £10 upgrade. Now for the serious stuff. The ride is smooth and very stable ,gear changing is accurate and fast. I have had no issues with the tyres and i have been out on a damp cold day and the bike gave me lots of confidence to hit speeds. The bike also looks good and not out of place with the high spec glossy expensive bikes i find riding round Epping Forest roads. The only tip i would give is that if you feel the bike gives you a posture which is uncomfortable then try a adjustable stem for the handle bar as that has done the trick for me.

used for 2 to 8 weeks I bought this bicycle for my wife who commutes to work everyday. It is quite decent and more affordable when compared to other options. Only thing I hated was the tires. They are not for commuting through a city like London. Neither are they 'all-season.' Probably that is the idea. They sell you a bike for a cheaper price with low quality/not-suitable equipment and make you spend money afterwards. After the first couple of days my wife has been coming home everyday with a couple of punctures, which is very very annoying. I am sick of puncture repairing every night. Tomorrow I am going to buy a new, decent pair of tires. As a result. this is a decent, value for money bike, ideal for commuting. But be prepared to spend between 30 and 50 quids for a new pair of tires.

Response of the brand

Dear Sir,
I'm pleased to read that you are enjoying your new bike.  Indeed, shimano sora groupset and carbon forks for this price is tough to find.
Regarding the tyres, the Hutchinson Equinox are good for dry or damp conditions.  I can assure you that these are not sub-standard tyres which we put on the bike to make you spend money afterwards.  The Hutchinson Equinox is fast rolling and would be perfect for longer rides in the dryer months.
However, you are correct in saying that if you commute and ride in all seasons it is well worth investing in puncture resistant tyres.  This would be the case with most road bikes you would buy.  one word of caution, they do tend to be slightly heavier and not as fast as the Equinox.
We recommend the Vittoria pro tech plus 700x25 tyres.  For only £17.99 each, they offer great value and performance for only £36 a pair.
Thank you for your feedback as I'm sure that other customers will take your advice to upgrade the tyres if the commute regularly in all seasons.

Excellent commuter

Carbon forks, Shimano Sora gearset, lightweight

Front mech difficult to set up, brakes average

used for 2 to 8 weeks After 8 weeks of solid commuting I'm more than happy with this bike. The carbon forks take an amazing amount of chatter out of the ride, and it feels light and responsive. I've ridden old steel frames all my life so this feels like a totally different beast, and I now wish I'd made the leap to a more expensive bike years ago. Only negatives; brakes are fairly average and the front mech caused me issues, with a slipped cable that I managed to snap after I had to adjust it mid ride. I took it back to the Coventry store and they sorted that out for me without any fuss though, so really good customer service from your mechanic.
