The Genesis Flyer goes disc, making it the ultimate foul weather winter bike, or sharp stopping city bike.

Based on the CDA frameset, a hybrid double-butted alloy tubeset is a clever mix of two differing grade alloys to help give high levels of stiffness in certain areas and compliance/ flex in others. Matched to the simplicity of the single-speed setup, this is one bike that minimises maintenance, cleaning and adjustment, leaving you more time to get on with riding.

Please note - Kit may differ from pictures, bike sold with Maxxis Overdrive 35c tyres

          Nice budget commute bike- and more.

          I bought this as a basis for a new commute bike for winter/ bad weather use and after a couple of months use I think it is going to be fine. Good value. I expect to upgrade some components in the first year or so. Have already had a new front wheel built with hub dynamo. Plenty of clearance for tyres left even after adding ‘guards. There are more mounting points that I expect to use- but maybe I'll take it on tour one day- who knows, it's capable of so much more than getting me to work. Hope to update with a long term test in 10 years!

          Simple Single Speed

          I'm enjoying my Genesis Flyer which I've now been using for a couple of weeks. I've notched up a couple hundred miles. Some out of the box issues to look at straight away would be to tighten all the allen key bolts. I greased mine too. Also the crank arms. They were making a grinding sound and I thought I'd need to replace the bottom bracket but tightening the crank arm bolts rectified the issue. The Allen key fixing bolt holes on the rear stays are 5mm not 4mm.

          Update review

          My previous review still stands, I'm well pleased with the 'Flyer' overall however, I've deducted a star for the following reason;

          A few rides in and I felt at times that I was trying to ride through treacle. Close inspection of the supplied Taiwanese freewheel, showed grease oozing out of the gaps and and a resistance to forward momentum. Further 'on line' investigation led to poor reviews of this particular freewheel. Its cheap and clearly built to a price point. With only one speed on this bike, I'd hoped Genesis would have spec'd something better. ( Have emailed Genesis about this but received no response).

          Anyway, swapped this freewheel for a Halo 'clickster' and it has transformed the ride, no more treacle effect and a great whirring sound when freewheeling. It was another £50+, but worth it. Also swapped front chainring for a Surly 38 tooth, which gives me a better cadence for gravel surfaces. Found the supplied 42 tooth OK for road but not as flexible off. Hope this helps others considering a purchase.

          What a fun bike to ride

          I fancied a single speed gravel bike, having been a 'fixie' rider for the last 20 years, but didn't want to pay an extortionate price to own one. Research led me to just about the only candidate, the 'Flyer' and I'm not disappointed. Of course, not being able to try or see one before purchase was a dilemma and there were few on line reviews. Having taken the plunge I'm extremely pleased. Bike geometry is far less aggressive than a previously owned cyclo x bike, it's just spot on, allowing for a comfortable ride, good handling and a position in the drops that is so sustainable. Disc brakes are a bonus and work well, gearing just right. There's nothing I can fault with this machine for the job its designed to do. Shame its only available in grey which, does look better in the flesh than on line pictures. For the money, its a 'no brainer'.
