Don't change gear on bumpy sections! My chain line is pretty bad in bottom gear too on the big ring and if I change on a rough bit it changes down to the little ring on its own...

I have been living in France for 41 years :) Back in the turbulent 60's and 70's I was in the anti-monarchy camp, my mother gave me my first name after a certain princesses husband... I would say probably more royal friendly than Australia but then NZ was colonised by civilised people and not a...

Answer: the power is identical, how it is applied to the rear wheel is different. When I had the hub motor bike I was always changing gears and assistance levels, I can't see any difference with a mid drive in that respect. I don't have issues changing gears in fact they change so quietly...

For me the ideal number would be 16 gears, 8 for going up hills even unpowered and 8 more for about 90% of the time. I am going to try just 10 to see if i can make that work but I will be cheating, I'll keep a granny chainring just in case.

Remember Sturmey Archer? Sunrace owns the brand now. If/when I go to 10 speed I will buy their 11-46 without hesitation, the 11-40 8 speed does it's job.

If you want to run it at 48v a controller out in the breeze would be my option. The motor seems to draw current differently from a hub motor, not more current, the same amount but probably ramping up more quickly. Some of the first testers had problems with weaker batteries and even I carved a...

I rate royal babies and abba at the same yuckiness threshold. Sorry!

Yesterday a very important business leader said on a TV show I was watching: "Once we have gotten rid of the English, thanks to brexit, the EU project will get back on the rails, many of its current problems are because the English wanted things done their way"... Well I never!

Precialps specialise in CNC aluminium. Careful it is for the second generation motors with 7 screws.

The GSM is better because you can choose the controller for it. Both are almost identical in that chainring spiders for BBS0x fit the GSM too. The Bafang is better finished and you can buy alloy secondary reduction gear covers.

All mid drives need to be in the right gear. I have stalled the GSM (once, very briefly) on a >15% hill when testing. I have since changed the chainring to a smaller one. The BBS01 has a 15 Amp controller that can be tweaked up to 18 A IIRC.

Abba announce first new songs for 35 years Will the pain never end! :eek:

But when you buy a Stromer you get a mechanic in the bike box! :)

Hi, I have been kicking the theory around for quite some time, here are a few random thoughts: - after discovering the stress that goes through a 26" trike rear wheel in corners a stock Chinese made wheel won't last long in my opinion - trikes go fast enough already on the flat so a vanilla 25...

"Louis"? Does that mean they are thinking of invading France again? Brexit, a prince called Louis, I'm sure there is something been put in the water... Remember to wash you hands every time you touch a door nob too! :p

Hmmm... That isn't supposed to happen the LCD should throw up an error message when an over voltage is detected should it not? I thought the Bafang controller was more intelligent than the KT's?

Cables? What cables? There! It can be done now get to it you lot! I cringe every time I see a factory made e-bike with brake cut offs...

Got a list of countries for us? What are you going to sell them? If, for example, I had been a NZ business man and if you gave me access to a market of 500 million clients on one hand and a market of 50 million clients on the other at me, which one do you think I would invest most commercial...

Next time you win the lottery drop me a line and I'll send you a parts list :)
