RocketBall Description

The folding electric RocketBall is part of the group of folding minifat models including the Fatty and Calipso, both with fat 20 inch tyres, and the Gran Calipso 24The more than 10cm contact patch provided by the 20” diameter wheels ensures surprisingly serene cycling on our daily trips, taking on bumps with complete comfort and full manoeuvrability on both open roads and city streets. You can pick between different customisation options for the RocketBall if you choose, including making it into an absolute city speed demon. It shares the same geometry and parts, except for the 2.1” wide wheels, as the Rocket model.

The RocketBall is powered by an intelligent rear hub brushless 8FUN 250w power rated and 45 Newton metre torque motor, with a 36 Volt and 17 Amp controller, and 1:1 PAS (Pedal Assistance System), which provides assistance up to 28km/h. If you choose, you can fit it out with another 8FUN motor, also mounted on the rear hub, with 500w and 80 Newton metres of torque, or a mid-drive motor. The mid-drive offers 48 Volts and 1000 Watts, which will stun the crowds as you fly by. All variants of the electrical system come with a 2 year warranty.

The on-board computer offers 3 levels of assistance and features an LED display that shows battery level and can turn on and off the electrical system and lights. For those who need more options for the pedal assistance, there is the option of a digital display that offers 5 levels and has the same features as the LED display plus a kilometre counter and the option to limit the top speed of the system.

A Samsung li-ion battery, which can deliver 10.4 Amps, supplies the electricity. The battery is built into the 6061 aluminium frame (5 year warranty on the frame) and perfectly protected from harm without affecting the overall design of the bike. The standard battery fully charges in just 4 or 5 hours with the smart charger that comes with it. Also available in 11.6Ah and 14Ah versions.

Riding the RocketBall transforms the daily adventure through the concrete jungle into a leisurely cycle thanks to the 20” diameter by 4”wide Kenda tyres, set on durable double-walled aluminium rims with steel spokes featuring copper reinforced heads. For even more comfort, it also includes Zoom front and rear suspension. Powerful front and rear LED lights also add safety to our night-time riding, whilst mudguards on both wheels ensure that our clothes will stay clean and tidy. Lastly, the combination of the comfortable, height adjustable Gel Cruiser saddle and the folding, aluminium ZOOM handlebar, which is also height adjustable, means that cyclists of all sizes can adopt a comfortable upright riding position.

To manage the RocketBall we have added a Shimano Acera 8 speed system for quick and easy shifts at all speeds as well as mechanical M375 brakes from the same Japanese firm with 160mm and 180mm discs on the rear and front wheel respectively. As one of the folding models, this electric beast will see you take on the steepest climbs and the chaos of city traffic in complete peace and comfort.
