Best derestriction for Bosch Active Line?

[SteveB1262]

My Motus continues to assist to at least 19mph and has continued up to 22.5mph but even at that speed using the 7 gear cassette I just couldn't pedal fast enough to increase the speed so cannot see the point of even bothering to derestrict it. It's probably a different matter with the 10 speed derailleur but it's certainly plenty fast enough for me.

you need a bigger front sprocket

sound wave - have you used those two speed / double sprockets ?

Saw some on you tube and considering for next summer...Small for off road .. BIG road road use...to bikes in one

i use them all the time tho the kit is expensive and only goes to 18t.

i have 20t and 18t on it atm but you just need this and a normal sprocket.

sorry bit confused...Do I use the kit from Speedup ( two sprockets ?) OR the one from eBay plus the original Bosch sprocket ?

it works with 11-12spd chains diy option but im not sure about lower speeds as the chains are thicker.

the 18t from speed up is alot thicker so wont be a problem but its expensive right..


i can sell the speed up kit if ur interested as not going to get used anymore.

I use the rs bike speed tongle hidden next to motor under casing. Never had an issue, correct reading and can be remotely switched on and off. I also used the wolf teeth sprocket but felt it was too close to casing so ended up buying an expensive larger Haibike sprocket.

if you get the sprocket in the link above there offset so you wont get that problem 14-20t and 15 quid
