PERFECT FOR STORAGE: The folding frame allows you to simply store the bike in the tightest of places like under a work desk, boot of a car or even into a carry bag when not in use, making the bike very managable when storing. The frame is aluminium keeping the bike incredibly lightweight at only 17.2kg.

IMPROVED BATTERY PERFORMANCE: Our partnership with LG has lead to the development of Advanced Battery Management which intelligently protects the battery from over strain when cycling up hill or into strong winds. The battery sits in the central top tube which protects the battery and will make charging far easier than most electric bikes. This in turn preserves the battery life much longer than most electric bikes. Our battery is capable of charging in 4-6 hours and can last up to 40 miles.

THUMB THROTTLE CONTROL: Giving the rider complete control over how much assistance they want from the battery. The rider can choose to have very little assistance or can let the battery do all the work giving the cyclist a effortless ride without having to change gears, and reach up to 20mph.

MULTIFUNCTIONAL LCD DISPLAY: Designed to keep the rider aware of their current speed, current battery status and the outside temperature. The back-lit display has also been designed to be completely waterproof.
