Cytronex Electric Powered Cannondale Synapse

Cytronex Powered Cannondale Synapse Tiagra Flatbar Electric Bicycle

The Ultimate High Speed Electric Road Bike

At 14.8Kg the electric Cytronex Powered Cannondale Synapse has a superb power to weight ratio and excellent equipment, including Shimano Tiagra gears and the new Busch & Muller Cyo 60 lux LED headlight.

If you want to get there fast, this electric Cytronex conversion is the e-bike for you!

Fitted with electric Cytronex Power assistance for multi geared bikes, when you want electric assistance just press the right hand Boost button. You can either select full electric power on the left or low speed for steep hills, cycle paths or sightseeing. Whenever you depress the rear brake lever or push the Boost button again the electric power stops immediately. For safety you need to press the Boost button to start again.

The Cytronex electric motor will stop and freewheel whenever you stop pedalling, resuming as soon as you start to pedal again.
