    A bit about us

    Welcome to our new website. We've spent a lot of time re-designing the site, listening to what you want and making the whole experience better. 

    You will notice that we use actual stock levels so you know when it's in stock and when it isn't. We have a fully integrated live stock system that handles stock from in store and online from one central database - plus we have live stock information from our key suppliers that allows you to see beyond what we have here within these four walls. This all helps to reduce the times you have to get an email to say what you ordered isn't available. 

    We know you're always looking for the latest stuff, so we work hard on bringing you hottest new stuff first. Available to order now with availability dates so you can place a Pre Order and get it before anyone else. 

    Our new Checkout process allows you to check out by creating an account, signing in to an existing account (your account from our previous site will still work), a "Guest" checkout so you don't need to create an account, lastly you can just Express Checkout with Paypal. 

    Finally our new shipping options allow you greater control on how your order is delivered with realistic delivery times - so you'll know when you'll get it. You get despatch and tracking information (when available) with all orders.

    Last of all if you have any questions, email sales@alansbmx.com or just call us on 01942 826598.

    If you have time please do some Reviews of the products you have used on here. 

    Thanks again for checking us out. 

    Alan Woods.

    Pre-Order

    With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

    You Pre-Order is prioritised (at no additional charge); meaning that, as soon as the product arrives with us, we can wrap it straight back up and get it sent out to you - it often never even hits the stock room shelves!

    Pre-Launch

    With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

    So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

    Fly Bikes 2019 Proton 21 FC LHD Gloss Trans Blue Description

  • Brand : Fly Bikes
  • Season : 2019
  • Code : FLYBK036BKLHD
  • Weight : 0.01KG
  • This year, we did our homework and refined the whole mid range bike line, cleaning up many of the details to make them what feel is better than ever, and more value for your money. First up, we got rid of the two-piece steer tube fork. Forks are the one area you shouldn’t mess with and we felt this was definitely a major improvement, we hope you agree. Along with the fork upgrade, Trebol headset, a stronger 510 chain, bigger bars and a taller stand-over, giving the bike a better overall look and feel. On top of that, the 2019 Proton now comes equipped with four pegs, shorter 13” rear end and shorter 28mm. offset forks for all you street dawgs out there. It comes with tan tires on the black model, and the final color is a gloss version of our very popular trans blue.
