2020 Whyte e-160RS Motor Cover Screws

[SteveT999]

Hi, can anybody please tell me the size of the 2 small Allen key screws which hold the Bosh gen 4 cover on the Whyte e-160 RS ? I took the cover off to clean inside and discovered one screw intact and the other was broken.

Thanks for your help

Good, that's what I needed. The design cover screws for the Bosch Gen 4 are clearly documented. @SteveT999 - the motor cover screws on the Bosch Gen 4 (which is what your 2020 E-160 RS runs) are

M4 x 12mm, and the official Bosch screw set for the Gen 4 design cover contains three of them.

Note the Whyte parts page lists a specific spare part code for motor cover screws (WHYE-45), so it's worth dropping Whyte a quick email to confirm nothing frame-specific is going on with your bike's variant. That said, M4 x 12mm is the standard Bosch Gen 4 cover spec and almost certainly what you've got.

Whyte also sells these as their own spares under part code WHYE-45 "Motor cover screws." You can source either direct from Whyte or pick up the Bosch OEM set from any eBike parts retailer.

One tip worth noting: use anti-seize on the replacement screw, especially if going stainless steel, as they have a tendency to gall or seize up in aluminium threads.

Community consensus here also leans towards adding a small washer under the screw head if the plastic cover has any signs of the screw pulling through.

Amazing, thank you so much for your detailed replay, it's very much appreciated.

Glad it helped, @SteveT999. Good luck with the repair - if the threads are damaged when you get in there, a M4 helicoil kit will sort it without needing a new motor cover boss.

Once again, thank you very much.
