Size chart

Here you will find the best approximate information on optimal sizing that we can offer. Sizing varies by the manufacturer, type of bike, and other variants but this rough guide should give you a match. Sizing can also be individually subjective so If you have any more specific requirements regarding this information, we highly recommend calling our expert staff on 01268 695877, coming into the shop or speaking to us via Chat/Message!

We also recommend researching the manufacturer of the bike you are interested in directly - many manufacturer websites now offer a dedicated fit/size guide where you can enter your measurements. We hope to offer this service on our website by late 2023.

The Stomper Ace from GT is ready to hit the trails with some great features usually found on adult mountain bikes. With front suspension, disc brakes and Shimano gears this bike has everything kids could ask for and more.

  • Improved geometry - GT bikes with the LegitFit system feature geometry adjustments to improve ergonomics for youth statures. The result: Increased stability, comfort and confidence for a wider range of riders.
  • Easier pedalling - GT bikes with the LegitFit system have their pedal positions moved slightly forward. The result: Makes it easier to pedal.
  • All Terra suspension fork with 50mm travel
  • Promax mechanical disc, 160/160mm rotors
  • Shimano Altus 8 speed drivetrain

GT has developed a new line of kids’ bikes that utilise its Legit Fit system and are designed specifically for those growing shredders. The Legit Fit system enables GT to build kids’ bikes that have narrower cranks, proper gearing and improved body positioning. All with the benefits of optimising pedalling, balance, and speed right from the start. Even better is that it’s a system that works for kids of all ages, no more needing to “grow into” a bike.

Customer Reviews of Les's Cycles

★★★★★

Les’s Cycles has to be the best cycle shop in Essex. All the staff are friendly and helpful.
A small store from the outside but an Aladdin’s cave on the inside.
Not at all pushy like big chains.
Will not be going anywhere else from now on
Thank you Les’s Cycles

Just got my e bike sorted by Les Cycles. They were brilliant. My bike is under warranty and the manufacturer wasn’t very helpful at all. Despite this Les Cycles persisted and managed to eventually get the part needed. They fixed it all up and now I’m happily cycling again. Would definitely recommend them. The after care they give is truly first class.

The best bike shop by far.
Order a bike late on a Saturday (11:30pm) and by 11am the next day it was built and ready for me to collect.
The staff were more than happy to spend time explaining all about my new ebike, never had one so I had alot of questions.
Very knowledgeable and helpful.
