If so, can you post the link?

Re: UBCO 2wd e-moped

People need to keep in mind that this aimed primarily at replacing farm bikes on the farms. Plus it is silent for those early morning starts they do without waking the rest of the household.

At least they have the sense to limit their wild machines to 250w. Lest they go crazy :roll:
NZ allows 300W and a throttle with no speed limitation.

Re: Mid Drive with Internally Geared Hubs

Thanks spinningmagnets. If I want to use a Cyclone and run 24" wheels, I know I need 420rpm at the wheel to run 30mph. How do I work out the sprocket sizes through the system?

EDIT: If I understand correctly I would need to be spinning the IGH at 840rpm in 3rd gear to reduce load on the IGH?

Re: Mid Drive with Internally Geared Hubs

Thanks guys, looks like the 3-speed is the answer then.

I have never done this before so how do I do the calculations to work out what gearing I need where, when using a 3-speed IGH as a jackshaft?

Re: Mid Drive with Internally Geared Hubs

Spinningmagnets, do you think the SRAM Automatix 2-speed automatic hub is strong enough to use as a mid-drive jackshaft? What do you think its limit might be?

Hi G! I've been working on a little project. I attached 3 trailers to my bike! It's been lots of fun, but I need ideas to improve my setup. I've towed up to 9 passengers in it, and when I'm going downhill, it's impossible to stop at times if the hill is too steep (I go slow of course for their safe...

Re: Bamboo / BBS02 / Nexus IGH

I heard that isopropyl alcohol can be used for curing. "Another method to reduce starches is to soak bamboo in Isopropyl alcohol (also isopropanol, propan-2-ol, 2-propanol, rubbing alcohol or the abbreviation IPA) This cheap liquid might be easier to use than to slow bake bamboo.

Re: Looking for motor advice for 30mph/50kph build

Thanks. I was thinking if I wanted to run a larger diameter like a moped 19" rim with 72V 40A, would the 6T MXUS 3000W be a better match? I know it would give away a little performance over the 5T with a 17" moped rim but should gain some range and still hit the speed. Apart from the Adaptto, what o...

Re: Looking for motor advice for 30mph/50kph build

Thanks everyone for your input. I originally started out with the idea of a 2000W 48V build but started to think this probably wasn't going to cut it if I wanted to be able to carry someone as well from time to time and yes, there are definitely hills. Looking for simplicity and low maintenance. I t...

Finally a 100mm BBS02 but now so many fat bikes are using a 120mm BB. Wonder if Bafang will offer a 120mm any time soon?
