chip für elektrofahrrad Yamaha Mid Engine EBike Chip Tuning Speedbox Evo2 – InterCyprus Trading Ltd

Upgrade your Yamaha mid‑engine electric bicycle with the CMX E‑Bike Speedbox Evo2. This compact, waterproof tuning box is designed to boost electrical assistance up to 50 km/h on compatible mid‑drive systems, giving you more confident cruising, quicker power when you need it, and a smoother ride on longer or steeper routes. Built for universal compatibility with mid‑engine motors from BOSCH, Kalkhoff, Impulse, Bose and Conti, it’s a practical solution for riders who want more performance without major modifications.

Easy to install and discreet in black plastic, the Speedbox Evo2 plugs into the original speed sensor and lets you adjust by repositioning the spoke magnet. When you’re ready to ride legally on public roads, simply remove the box and return the magnet to its original position. The unit starts to halve the speed sensor signal around 20–23 km/h, enabling assistance up to 50 km/h, with a downshift point at about 18 km/h. The device features a programmable interface for fine tuning, a compact footprint (54 x 46 x 20 mm), and a robust, laser‑sintered housing for durability. It’s microprocessor controlled and designed with highly efficient energy management that saves around 30% of energy while supplying higher assist when you need it.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Trusted by riders since 2002 for reliable gear and service, InterCyprus continues to deliver practical, performance‑focused cycling accessories you can depend on.
