I got them for my StereoHybrid ONE77HPC SLX2025 cube ebike. Good and sturdy, excellent purchase.

Adrian

These arms are very nice. High-quality workmanship and fit perfectly with the Bosch Gen 5 motor. I installed them on my Cube Hybrid Reaction 2026. The rubber seal on the right pedal protects the motor from dirt. Rubber caps on the ends of the arms protect them from scratches and rock impacts. I recommend them.

Good morning, which arm offset will fit the Bosch Gen 5 engine? 24mm or 26mm? Thanks for the reply.

I have a Cube with a Bosch 5th gen motor and I replaced the original cranks with 26mm E-thirteen cranks. They fit perfectly.
