  • Great quality price

  • Great value speedster transport

    Bought for my 14 year old son to speed up his getting about versus a pretty light but inherently slow 26er mountain bike. He didn't want the hoops of a full on road bike and the weight of most hybrids at the price point was high. Solution, the Triban flat bar. Road bike weight/speed without the hoops. Keep the 26er mountain bike for when needed. Hybrids are neither good off road or on.
  • Still hopeful.

    Tried to order this bike online unsuccessfully. Checked with Decathlon who emailed that Triban 520 flat bar was no longer available. Upon visiting Decathlon at Oxford I found this was not the case (!). My size was not in stock so placed order online using the stores own ordering system assisted by very helpful staff. Much confusion followed - too lengthy and boring to relate - avoid Decathlon's online ordering service if you can. Bike arrived - packed and prepared very differently to the website video, (ex demo?) but fine. Nice machine. The problem is the gears. Ok changing from lower to higher. Higher to lower ? the change is either delayed or doesn't happen at all. Advice please.
    I cannot recommend it as things stand.
  • Excellent bike, Excellent price.

    I really wanted a road bike with a flat bar, and this bike met my budget and my needs. Quick, lightweight and with decent parts for the price. As many reviews attest this bike is extremely good value at this price point. Would recommend to anyone wanting a road bike without drop handle bars.

    Hi there, Bought this bike with flat bar. Light and comfortable to ride. Just wondering can I put hybrid wheels with bigger tread? If so which one would you recommend from your shop? Thanks
