Hide it inside...

This is one of the newest systems from Protanium. We use a frame with a special developed and strengthened down tube. The battery can easily be taken out. On this bike you really have to pay attention to notice it’s an electric bike.

The geometry of the frames is beautiful and the riding feeling is fantastic because the weight of the system is in total harmony and balance.

We have final frames to choose from. But it is also possible that the down tube system can be added to an already existing frame you have in your program. Simply just by changing the down tube.

Charger systems

Protanium offers different charger systems. Depending on the battery you choose. The normal house charger is a 2 amp charger and Protanium super fast charge system is a high power charger on 50,4 amp. It can recharge in minutes.
