I bought a Rockguardz bash guard for my 2021 Cube with Bosch CX motor and am quite satisfied. Ordering was fairly straightforward even though I purchased from Canada and needed to be very certain I got the right product - I did. It took 3-4 weeks in total but that was okay considering international shipping. The guard fit well but is only secured by its close fit and a velcro strap. I was leery that it would hold given the very rough terrain I ride (many logs, roots, rocks) to cross. It has held most of the time but it did slide down at one point with a 1cm gap of air between the new guard and the bike’s original plastic motor guard. It’s only happened once right after I installed it so maybe it was a break-in thing and holds better once the Rockguardz’s been in place longer. I actually installed another thick truck tire inner tube band over top of the Rockguardz strap and knotted to hold it secure. Not sure it is needed but better safe than sorry. I would recommend this product and am very pleased Rockguardz provides this product because the plastic motor guard supplied by Bosch is garbage and a laughing stock they should be embarrassed about. I’ve broken many but hopefully no more now Rockguardz seems to have come to the rescue.

Didn’t fit snugly made for previous model Merida before the changed battery cover

The protector fits perfectly on the frame giving it very good protection against knocks and bumps. I do miss that it has a hole aligned with the hole in the frame to drain water and mud inside the frame. Highly recommended.
