Kaiser Carbon Folding Electric Bicycle - 12.8kg


If you're looking for the best quality electric folding bike possible then the Kaiser has solved your dilemma. The Kaiser'frame is not only made entirely from the best carbon available but has been designed with geometry designed to contribute to the Kaiser's exquisite control and finely tuned feel that has been achieved as the result. Imagine riding a folding electric bike weighing just 12.8 kilos with the thrust of a powerful 45 Newton meter motor powered by a Samsung battery. You've got it right - it's a delight.

A bike equipped with a powerful, reliable electric system, tested for more than 15 years in the different possible conditions, mounted on a carbon frame of the best quality, and with 5 years of warranty that makes you can have in your hands the Kaiser electric folding model with the same push system as the other electric folding models, but with only 12.8 kilos of weight, something incredible if we talk about an electric bike.

To achieve this limited weight, which you will find impossible to find on any other electric model, whatever the range and price, the entire assembly of the Kaiser has been carefully thought out.

Shimano MT200 hydraulic brakes cooperate with the overall package of the Kaiser, contributing to the smoothness and efficiency of braking, as such a light and powerful model needs brakes that are up to the task.

The gear system could not be left behind, in this electric hybrid halfway between urban and road without forgetting that it is also foldable, the fabulous Shimano Sora 9-speed gears have been chosen, gears used in conventional road cycling for their smooth shifting and their different developments optimized to extract the maximum in each pedal stroke regardless of the situation in which we find ourselves.

From the digital display, we access all the parameters relating to the route, control, and manage the entire electrical system and lights.

As an option, we can add long mudguards on both wheels and the rear luggage rack to carry loads of up to 25 kilos with ease.

Kaiser stands out for its incredible performance and design within its category of electric folding bikes, finding no close rival that can come close in terms of weight, quality of carbon frame, the pedigree of all the components that make it up as well as the unparalleled feeling of comfort in motion, with a ride so fine that you will seem to be pedaling on a stationary bike in your living room while you devour miles and miles in the entertaining urban jungle.
