Adjusting cones/bearings on hub motors?

[DynatechFan]

Hoping to build up my new (first) ebike kit at the weekend - as a slightly obsessive mechanic I service the hubs on my bikes fairly regularly and would always grease the bearings and check / tweak the cones on a new wheel

My new rear hub drive doesnt give me access to the cones - there physically isn't the space to get a spanner to any cones that might be there - so I wondered, are geared hub wheels typically the sealed bearing type?

All non-adjustable bearing races. The main cause of trouble is water ingress. The bearings are cheap and easy to replace as long as you can open the motor. Some need special tools to open.

thanks d8veh - time for some careful application of CL grease in the axle spaces then

The water goes in down the motor cable when you install the wheel the wrong way up. It can also go in through the disc fixing threads if they're not sealed and the holes aren't blind. With cassette motors it can go in down the back of the cassette.
