Re: Good quality throttle

Good things have been said about the grin half twist ones, and they are quite stealth too. https://www.ebikes.ca/shop/electric-bicycle-parts/throttles.html If you're talking about the slim half twist, then I have gone through 3 of them and they last a max of 3 months before the spring is shot. They...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I have a 4t leaf with a temp sensor installed from the factory. I also have a CAv3.... How do I make the two work together?

this is the cyc X1 which would have been quite obvious to you if you had read the thread title.
The thread title says gng/cycmotor. So it has both in the title.

I'm a bit confused. Is the gng and cyc the same motor? The gng looks like a cyclone, while the cyc looks a bit smaller

Re: Christiania Bike conversion

I know this thread is quite old. I did a conversion of an aluminium Christiania bike with the kit from boxbike above (BEWO 36v 350w). I’ve done over 2.000 happy km on the bike, but now the bearings inside the mid drive hub is roasted. It seems like the bbs02 hub is more reliable, but seems impossib...

Re: Torque arm thick enough ?

I would say that is more than enough for only a 1000w hub, but it never hurts to be thick. I would, however, put one on each side though like you say.

Re: Compact Field Oriented Controller, ASI + Grin, limited run

What is your max Regen Battery set to? And is the batter fully charged? The regen works once the battery voltage drops a bit from full in my experience. Oops, didn't realise that pop-up was there, but it's set at 6v (I think). I actually just reloaded the default settings, did an auto tune and now ...

That is a 9C or a 9C clone which can be a pretty fast motor and be used at fairly high voltage. Where are you located?

Hub motor bounce

I was wondering what would cause a rear hub to bounce? I put my bike upside down and hit the throttle and the entire bike shakes. Looking from above, the wheel seems pretty true, but I'm assuming it's not? Is that likely the problem?

Re: First build and would like a second set of eyes....

Personally I would find something with at least front suspension. The battery choice seems good and yes it has a lock. Since you're ordering from em3ev anyways, you might as well get the 5A charger. The option to charge to 90% will increase the life of your battery The blue gear will most likely be ...
