Bosch Motor Upgrades
MudStop “Bosch Gen 2 bearing protection”
MudStop sealing system was designed by VeloLab to ensure better protection for the vulnerable main motor bearing on the Bosch Active and Performance Line / CX motors (Gen-2 motors). Unlike the Bosch protection seal, the MudStop completely covers the entire main motor bearing and outer casing. This stops water and contamination getting past the cover and entering the bearing. When used with the custom made crankshaft seal, it makes your motor as protected as it always should have been Full information and instructions can be found here:

This is a durable double lip seal, specifically manufactured to fit the Bosch crankshaft. An effective waterproof barrier for the Bosch right-hand crankshaft bearing.

The PLB Brose Motor Upgrade
About the Upgrade
At eBike Motor Centre we noticed the failure rates of the Brose motors has been widely reported and discussed on forums and social media platforms all over the world. We could also see from our own experience, and the sheer number of Brose motors going through our workshop that there were a few issues that needed addressing. Particularly when used off road. Although Brose have been working hard to address some of these issues, that does not really help those outside of the warranty period. So we decided to do something about it!
We can now offer an upgrade for all Brose motors. The upgrades we do includes the following:
Uprated thicker, stronger, Brose carbon fibre drive belt.
Uprated heavy duty sprag bearing for the motor drive pulley
Uprated heavy duty sprag bearing for the crankshaft drive
Single lip rotary shaft seal to stop water ingress into the crankshaft needle roller bearing and beyond (This also stops rust damage to the crankshaft bearing surface and premature failure of the crankshaft needle roller bearing)
Genuine Brose bearing cover seal for the right-hand crankshaft ball bearing (not fitted until 2017)
Waterproof long-life grease packed between outer bearings and motor covers. (This helps stop water sitting in these areas and seeping into the outer bearings)
We also fit an external X-ring seal each side of the crankshaft to further stop the chance of any water ingress into the motor
We remove the two ECU cover screws and seal these to stop water ingress into the ECU
and finally, we treat and coat the motors electric plugs to stop corrosion and water entering the ECU by capillary action along the wires
