Charity Impact

Buying this bike will allow us to give 4 refugees a bike (plus a lock, helmet, and light set) so that they can cycle safely in London. Read more about our mission here.

Professional view from Stu

Here's a little fact for you. This 6KU single speed is the number one best-selling urban bicycle! Now, how about that! If you're searching for an affordable, reliable and comfortable, yet dashingly good looking bike, this is just what you're after. And given it's available in such a wide range of snazzy finishes, you can be sure to find the paint job that suits you perfectly.

Constructed from lightweight, vibration dampening steel and without all the unnecessary components to weigh you down, the average weight of these 6KUs is just 9kgs! That's less than many road bikes! And as long as you're not planning on climbing up any alpine passes, the one gear is fine for the vast majority of city riding. These single speed bikes are the choice of seasoned bike couriers who value them for their simplicity, reliability and agility. They just work, month after month, year after year with relatively little maintenance. They don't have complex and heavy derailleurs and gear shifters that can so easily stop working, especially if they’re ridden a lot in wetter weather.

This model boasts a 'flip-flop' rear hub meaning you can easily switch between a freewheel on one side (allowing you to coast) and a fixed gear on the other. This means you can moonlight as a track cyclist! You've got a front and rear caliper brake with super comfortable  brake levers and handlebar grips. And finally adding a bit of flare are some rather fetching 30mm deep section rims for those marginal aero gains!

This is a brand new bike that has been carefully built up by one of our professional mechanics. Once built, they'll undergo a comprehensive check-over and tune-up service to ensure they're race ready!

Best for: Affordable city riding in style

FAQs
Products
  • What can I expect from your second hand bikes?
    It's our solemn promise that our bikes will work as well as they did when they first rolled off the production line. All bikes are given the gold standard service by our crack team of highly trained, highly experienced mechanics, and (assuming you treat it right) your bike will be good to ride for many years to come.

    Here's what you can expect from your new-to-you bike:
    • The frame will be second hand. Aesthetically, there may be some cosmetic wear so if this is a concern for you make sure you have good look at the photos before you buy.
    • Some of the other components will also be second hand – but anything that doesn't meet our strict standards will be replaced with brand new parts. This goes for everything from the handlebar tape to the bottom bracket.
    • Fast-wearing elements, like the brake blocks and gear cabling, will be completely overhauled and braking and gear shifting will be super snappy, just how you like it.

    If you have any doubts at all about buying a bike from The Bike Shop, then just give us a call. If you're in London, feel free to pop into the workshop for a test ride. And remember that we offer a 14-day test ride money back guarantee if you decide you don't like your new bike.

    We want to make you feel as comfortable buying from us as you would buying from a trusted friend. The only difference is we've never met, we don't know you from Adam and we're doing this all over the amazing internet. We've had hundreds of happy customers – it's gonna be sweet.
  • How do I know which size bike I need?
    Good question! This is kind of important and depends on your height and the type of bike you're buying. So please please please check out our size guide (link) before you put down any of your hard earned cash. And don't try and squeeze onto a bike too small or too big for you – you'll just end up looking like a circus clown and wrecking your knees / back / street cred. Thanks.
  • Where did my bike come from?
    All our bikes are donated to us and come from a variety of sources including the police, local councils and kindly people like you. If you're replacing an old bike you don't want any more, why not keep the virtuous cycle going and donate it to a bikeless refugee? Unfortunately, we can't do part exchange but rest assured that you're now our number one customer!
  • Can I test ride a bike before I buy it?
    Due to current circumstances we unfortunately cannot offer test rides at the moment. However, we do offer a 14-day test ride, no fuss, no fret returns period from the day you received your order on all bike orders online. If you decide it isn't the bike for you, all you need to do is pack it back up and return it to us and cover the cost and organisation of the return. We will process the refund, via the original payment method, once the bike has arrived back to us safely and has been checked over by one of our mechanics.
  • Will my bike be safe to ride?
    Thanks for asking this not silly question. Buying online can be scary, but let us reassure you that our mechanics are all highly qualified and extremely experienced. They give the gold standard service to every bike we sell and make 100% certain that it is not only safe, but a pleasure to ride.

    We're so utterly convinced that you'll be happy with our bikes that we offer a 14-day test ride returns policy. If you're not ecstatic with your new set of wheels, just box it up and send it back for a full refund. No problemo.
  • Do all your profits go to charity?
    Absolutely! 100%. Every single penny we make helps us get refugees cycling. A bike can utterly transform a refugee’s life by gifting them a free, sustainable and empowering way to access essential resources and services such as education, healthcare and psychological support. With a bike, we reckon refugees are more likely to get back on their feet and ultimately make positive contributions to society. For more on the how, what, why of our mission, check out our website.
Delivery
  • When will my order arrive?
    Due to COVID-19 challenges and the additional demand for bikes and accessories, our delivery times are longer than usual, so it may take up to 14 days for you to receive your order – but rest assured we are working as hard as we can right now to get your order to you

    We'll send you an email as soon as your order has been sent on its merry way - your order should then be with you within 1-2 working day

    Please note: We only deliver to the mainland UK. Sorry!
  • How will my bike be packaged? Is it fully assembled?
    For deliveries outside of London, your bike will arrive in a massive cardboard bike box. Because cardboard boxes aren't bike-shaped, however, there will be a couple of simple fixes and adjustments to make before it's ready to ride.

    This may sound intimidating, but don’t panic. To help we've made some videos for you to follow along at home. Get the whole series plus instructions on our dedicated page: How to assemble your bike.

    If you're not sure or you've got any questions at all about how to put your bike together, don't guess – get in touch! Finally, fold the box flat and keep it safe just in case you need to send the bike back to us.

    If you notice that the box is damaged when the bike is delivered to you, you must either refuse the delivery, or register the damage with the delivery person. If a bike is tragically damaged in transit and that damage isn't registered, we've got no way of making a claim with the delivery company to recoup costs. And that's rubbish.
  • Do I need to be at home when the bike is delivered?
    Yes – you will need to be at home to take delivery. Plan to work from home, download a box set or spend the day clearing out the garage. It'll be worth it, we promise!
  • How much does delivery cost?
    Delivery to the UK Mainland is totally free for all orders over £20, what a winner! For any orders under £20, there is a small charge of £3 per order.

  • Where do you deliver to?
    We deliver to anywhere in Mainland UK. That includes England, Wales, anywhere in Mainland Scotland, as well as Portishead, Ullapool and Ormskirk.

    That sadly does NOT include any of the British Isles - not the Isle of Wight, not the Isle of Man, not the Isle of Skerry. Sorry, but bike delivery gets mega expensive with the couriers as soon as they have to get on a ferry. Gutted.
  • Can I pick my bike up from the shop?
    Our shop is currently closed, however you can pick up your order from our workshop in Deptford! Just select Click & Collect when placing your order online and we will contact you once your order is ready to arrange an appointment. Collections are strictly by appointment only. Due to COVID-19 challenges and the additional demand for bikes and accessories at the moment, it may take up to 14 days for us to prepare your order.

    The address for collections is: The Bike Project Workshop, Railway Arches 215-216 Edward Place, Deptford, SE8 5HD.

    *Please note our workshop is open for collection appointments only. We are unable to offer test rides, returns or exchanges, or any sales that haven't been placed online in advance from this site at the moment.
Returns
  • What can I do if I'm unhappy with my bike?
    Oh no! First up, tell us about the problem on the phone (020 7733 8098) or in an email (info@thebikeproject.co.uk). Fingers crossed our bike agony aunts and uncles will be able to fix the problem for you.

    If you're still within our 14-day test ride no fuss, no fret returns period, then you can always pack the bike back up and return it to us.

    Please note: If there is a fault with your bike, then you have up to 30 days to notify us of the problem.
  • How do I return my bike?
    If you're reading this before buying your bike: stop now and double check our bike size guide. Our number one rule for customers is to make sure you're buying a bike that will fit you. If you've got any doubts or queries about this or any aspect of buying a bike, give us a call or send us an email. Prevention is better than a cure!

    If you're reading this because you're unhappy and want to return your bike, then shucks! We're sorry you feel that way and doubly sorry if we screwed up.

    If it's still within 14 days of the delivery date then no problemo – you can return the bike for a full refund. For any orders made in December, we extend our returns period until January 15th just in case it was a Christmas present!

    Please note: If there is a fault with your bike, then you have up to 30 days to notify us of the problem.

    Send us an email ASAP (info@thebikeproject.co.uk) announcing your intention to return the bike. Although we offer a full refund for the cost of the bike, we can't afford to cover the cost of the return. The organisation and cost of returning the bike safely to us is your responsibility.

    The best way to do this is to keep the box and re-pack in the same way it arrived. Please contact us if you need advice on how to pack the bike, but we advise you to:

    1. Remove the pedals.
    2. Turn the handlebars.
    3. Wrap the forks in cardboard to protect them from damage during shipping.
    4. Fill out the box with spare cardboard to make sure the bike won't rattle around in the box.
    5. Mark the box as 'Fragile' and attach our delivery address in a clearly visible location.

    If the bike was damaged on delivery, you must either refuse the delivery or register the damage with the delivery person. In this case, we can make a claim with the delivery company to recoup costs and you will, of course, receive a full refund.

    We will refund the cost of the bike within 7 working days of its arrival in our workshop. This gives us a chance to give it the once over and get the money back in your account.
  • I'm not happy with my accessories - what can I do?
    Don't fret - if you're unhappy with any accessories you've bought from us, for any reason at all, you have up to 14 days after purchase to return them, provided it has not been used or fitted, and is returned in its original packaging with a valid proof of purchase.
