Technical specifications

Easy to ride.

Bike 43 is easy to get on and enjoy due to the low step frame. You can also opt for the speed lifter to adjust the handlebar and seat height. This bike is your one size fits all solution.

Technical specifications

Compact Size.

The bike is only 10cm (4″) longer than a regular bike. It’s just as easy to park, even vertically at home, and fits on a car bike rack to take it with you.

Technical specifications

Double X Design.

The double X design of the frame offers stiffness where and when you need it. Turning, braking, and accelerating comes naturally for all cyclists.

Technical specifications

Lifetime warranty on frame.

Not the basic steel or aluminum you’re used to. We went for lightweight CrMo steel, well known to be a “living material” that absorbs shocks generated by road irregularities. Ultimate proof of quality, the frame is guaranteed for life.

Technical specifications

Low center of gravity.

Low center of gravity thanks to a small 20″ rear wheel and a very low battery position.
Comfort – The larger 24″ front wheel goes smoothly over city obstacles by rolling over them rather than bumping against

Technical specifications

Multi-motor compatibility.

Best of all, the bike isn’t locked to a specific type of motor. It can easily be evolved by changing it to a new model.

Technical specifications

Internal Gear Hub.

Internal hub for unbeatable reliability, forget about getting your hands dirty for chain drop. Easy gear change even when stopped and no maintenance. Choose between manual, eShift or continuous gears.
