The Allen Sports Ultra X Superlight Carbon bike is one of the best superlight carbon folding bikes in the market today. The bike is designed very well since the hinges and the locking mechanisms are all incorporated in it. And when it comes to folding bikes, they are mostly heavy not the Ultra X since it only weighs 18.75 lb (8.5 kg). It is one of the lightest folding bike in the market today.
The frame, fork, seat post, handlebar, stem, rims, crankset and saddle are all made of carbon fiber that's the reason why it is so light. It also features 451 wheels, and an SRAM X9 20-speed drivetrain (with a Shimano front derailleur) which gives you a smooth, responsive ride. It is the ultimate folding bicycle for city commuting or long distance rides. The 20 Speeds gives its rider a wide gear range designed for high speeds on flat terrain, climbing hills and everything else. Taking on sharp corners and avoiding road potholes is easy with this bike.
