So the bike originally had a cassette but the hub is threaded so I thought I would buy a 9s freewheel. A 7s freewheel came with the kit. I didn't really want to downgrade but I've got the brake side working now thanks to all your suggestions just that now the freewheel is too big and the spacer I do have is quite small and doesn't seem to be much room after the brake caliper is aligned. So I'm contemplating downgrading to 7s do I need to swap gear switchers or can I keep the gears I have an just never go past 7 or 6 which ever one it is?

Thanks that is helpful!

Cool thanks much appreciated. I have to get to work for a 12 hour shift but plan to sort this tomorrow. I've also ordered two torque arms which should be arriving tomorrow as well.

Thanks for your replies. Yes, it did come with two washers. I placed the washer with the lip into the dropout space then place the washer and tighten the bolt on the axle. Is that the correct way. The kit didn't come with instructions. I've been using YouTube videos to install the right side pas which is magnetic. I haven't specifically found a good one on installing a rear hun motor as yet. The search is ongoing .

I've had this bicycle unridden sitting in the garage for over 5 years. This is my first conversion experience. I bought the sutto 36v 250 watt rear hub motor from varstrom a batangas subsidiary. I believe I made a mistake as to the compatability. I installed the tyre had to widen the dropouts with a metal file. Then noticed that the disc brake rotor was scraping against the IS adapter that the hydraulic break needed to attach to the bike frame. So I tried filing down the side of the caliper adapter. I then thought buying narrower rear break may suffice so I went for a cabled rear brake because it seems that I may have to replace both hydraulic breaks with mechanical. The kit came with a 7s freewheel. I wanted to keep the 9s so I bought a 9s freewheel which I think hasn't helped with the brake caliper so I would like some advice please on what I've mentioned already and my bike has 27 gears 9s 3 settings. How do I make the 7s freewheel compatible with a 3x9s gear shifter? I believe I need to buy a torque arm which I will invest in. The caliper is part of Clarks brake set. Any help would be great! Thanks
