Bought for my Cube Hybrid 160
As long as you remember not to rush as you start and stop, this things is a god send !
So glad I invested in this unit! The Speedbox 1.1 B.Tuning, in my case for the Bosch Gen4 Performance Line CX motor coupled with a 750wh battery in this beautiful brand new Cube Reaction Hybrid Pro 2024 model e-bike.
No more drag feeling once hitting 16.2mph and you are able to custom select the speed limit from the Speedbox app once you download and install it on your smartphone device. Ran into a few problems in receiving the Speedbox unit, emailed the support staff right away and they rectified my issue in as little notice as possible.
Extremely happy with the purchase overall, and will definitely seek to recommend, and use the site again!
Thanks again, George! - CEO of Ebiketuner!
