Villiger Dynamic

Introduction

Villiger Dynamic is an innovative company founded in Switzerland by a team of both passionate e-bike riders and technology enthusiasts. Our experience on alpine trails has shown us that conventional e-bike drives are not providing the desired comfort. That is why we are developing a revolutionary drive that makes gear shifting obsolete.

This new drive allows the rider to stay at the optimal cadence level at all times, providing an unrivalled level of riding comfort both in alpine terrain and on the road.

Highlights

Unrivalled comfort and revolutionary riding experience.

Variable:	No more gear shifting required
Intelligent:	Automatic adaptation of the transmission to the terrain
Sustainable:	Power recovery when braking & driving downhill
Comfortable:	Start your ride on a hill without the bike rolling backwards
Simple:	No gear shifter on the rear wheel required

Description

Mid-motor with two electric motors and continuously variable transmission
Motor 1 supports the rider
Motor 2 continuously adjusts the gear ratio using planetary gears
Standstill control - bike does not roll away, even without braking!

rear wheel remains stationary, possible through the counter-rotating motors
controlled start with motor assistance straight out of standstill – feels like driving up a slope in an automatic car!

Advantages

Continuously variable transmission (seamless)

less than 0.5s from lowest to highest gear ratio
adapt transmission ratio at 100% full load
no gear shifting noises, no interruption
no “stepping through” with pedal when shifting gear
unlimited total transmission range (over 1000%)

Intelligent control dynamically adjusts the cadence to the driving behaviour

driver can preselect the cadence
computer adjusts the cadence & gear ratio depending on the terrain

Energy recovery during braking & downhill driving (recuperation)
Reversing by pedalling forwards: Ideal for cargo vehicles
