Ok thanks, I’d be looking to use a sw900 display and then I could just buy an additional 48v controller

Thanks for advice about the motor- I can see 250w kits although They say 36v, would this still work with a 48v battery? Just change the settings? Is a 250w still a direct drive ? Thanks for all your help, Ian

I never thought of that , excellent advice ! I just need a few mm deeper not wider (it’s a trek not a carrera subway, I just searched about filing and found this thread) . cheers again

Hi there, does filing the dropouts ever affect the disc brake? Does it throw it off or is there usually still enough play in it to work without more adjustment? I’m looking to get the axle probably 2-3mm deeper into the dropouts (rear)

Hi guys. Turns out I was being really stupid, the phase wires that I took out the little joining block (to get some washers over and left them loose) were randomly touching causing the juddering, when I moved the bike they must have moved enough not to touch to let it spin freely . Thanks for everyone’s help and especially the guy who mentioned phase wires

This is even when there is no power to the motor? I’ve not even connected battery yet

Flat terrain , mix of roads and paths , around 20miles range with most usage between 15-22mph

Yes I never thought of that , perhaps a smaller 250w motor with a bigger controller and battery

I will double check for wobble but sure it felt pretty solid , but I will need to try and wiggle when it is shudder and when it stops . I will check with battery once I have fitted but I’m expecting it be the same

Ok thanks, I will check with power and see what’s happens

Just a standard hub motor, 1000w , I’m not sure the exact term? I’ll try attach picture ,

Yeah when spun both ways . It’s not a geared hub motor though if that makes a difference. If I spin backwards And forwards a few times it sorts itself for a wee while . Is it likely to do the same when I connect battery?

A little update on my greenlance battery - I’m at 1700 miles no issues so far , still getting great range on a single change. My round trip is 22miles and manages this fine although I sometimes top up at each either end . Cheers

Hi guys. my new hub motor is juddering when I spin by hand , I can then rotate opposite way for a few turns then spin other way and it will be fine for a wee while . I’ve not connected better yet , any ideas? thanks guys

Sadly pics won’t upload, I’ve fitted 3 washers internal of the frame and that seems to have solved it. Is that to many washers ? I will be fitting at least 1 torque arm also , possibly 2 if that’s what anyone recommends , Thanks again
