Alpha V3 questions

How do Alpha V3 and Nova V3 differ?
Nova V3 offers step-through access for easier mounting. Alpha V3 retains the Alpha frame layout. Both have a 48V 25Ah Samsung-cell battery, adjustable dual suspension and GPS connectivity.

Will every ride reach 120km?
No. Up to 120km is not a guaranteed distance. Load, assistance level, hills, speed, wind and tyre pressure affect the distance between charges.

What does the GPS app do?
The specified system supports bike location tracking, movement monitoring and remote switch-off.

Can I use my existing child seat or trailer?
Yes. Child seats, trailers and carrying accessories that fit Alpha V2 also fit Alpha V3; those that fit Nova V2 also fit Nova V3. Both V3 models fit the Hamax rear child seat and our child trailers. Alpha V3 also fits the Alpha front child seat.

Explore our family e-bike and child-seat guide for setup ideas, or compare e-bike locks. Both V3 models fit the Hamax rear child seat and our child trailers. GPS does not replace a physical lock.
