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 help give you an idea. 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 or coming into the shop.

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 on official websites.

As one of the BIGGEST Independent UK Bike Shops, Les's Cycles process multiple Cycle To Work scheme orders everyday, dispatching bikes across the UK. All voucher related sales are subject to availability and our discretion to accept them*

IMPORTANT NOTE REGARDING SALE BIKES: Any bike that has been reduced in value still CAN be acquired but customers will need to cover the fees imposed on us by the scheme provider(s), listed below. Unfortunately the charges imposed by scheme providers are very high, much higher than usual transactional fees. There is no flexibility with this and we only offer sale or reduced products on scheme services as a gesture of goodwill to our customers.

You can either add the surcharge to your voucher total or pay it separately.

Example scheme provider fees for SALE PRICE ONLY** bicycles;

WE RECOMMEND: Gogeta.bike: 4%

Greencommuteinitiative.uk (GCI): 5%
Bike2workscheme.co.uk: 10%
Cyclesolutions.info: 10%

Vivup: 12.5%
**Cycle2Work: 15% (a fee may be payable on some full price models)
**Halfords Cycle2Work: 15% (a fee may be payable on some full price models)

To get started and place an order:

SEND US A EMAIL - We'll need you to provide details on the scheme you wish to use and the bike and size required so that we can confirm its available. If you are not ready to immediately proceed, you will be advised to place a small non-refundable deposit to hold the bike. The deposit will be refunded upon completion or cancellation. If after six weeks you do not redeem an order with us after reserving a bike, deposits are non-refundable and can only be converted to store credit.

For more specific information on any scheme or to ask if we can accept an unlisted scheme, please contact us or visit the shop!

A better way to produce aluminium

Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

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.
