INNOVATION
CONTAVELO's transmission module for electric bicycles has adopted a new mechanical concept.
Only slightly ‘CLICK' the pedal
in the reverse direction,
“Shift completed.”
In the case of the existing drailer method,
components such as shifter, cable, drail, and inner chain are required, and a setting process by an expert is required as well.
On the other hand, our product has a novel structural idea that integrates them into one complete module, meaning that chain shifts are no longer required.
Personal Mobility is reaching a new stage.
CONTAVELO's new ideas
have already been validated for mechanism and will guide you and your customers to enjoy a new quality of life.
All the CONTAVELO’s products are
free from deformation and breakage and
ensure high quality.
1st Gear
[It is called a low gear and is mainly used when climbing a slope]
- When the pedal rotates once, the inner ring(small gear) also rotates once.
The ratio of cogs between the big gear and the small gear is 1 : 0.75,
so the speed is reduced by 0.75 times compared to the 2nd gear despite the same one rotation.
Accordingly, the pedaling force is proportionally reduced.
[Because the gear ratio is 0.75 times, when the pedal rotates one revolution,
the chain-ring rotates 0.75 times. It has the same effect as using an inner chain-ring which does not actually exist.]
2nd Gear
[It is called a low gear and is mainly used when climbing a slope]
- When the pedal rotates once, the inner ring(small gear) also rotates once.
is harder to pedal although the speed is high.
