Re: Sur-Ron - New Mid drive Bike

Dunno about hearing loss, I used to shoot machine guns without hearing protection and listen to loud music and riding really loud bikes - my hearing is still perfect when tested. After all that, doubt that I will get hearing loss from e-bike rides.

Re: Sur-Ron - New Mid drive Bike

I finally got some instrumentation installed on mine: Img_0964.jpg Cycle Analyst is tied in now, but only measures the current going to the controller and not the dc-dc converter. I found the switched pack voltage line coming from the key and picked up one of the hall sensor signals for speed. I'm ...

Re: Sur-Ron - New Mid drive Bike

Maybe 2 chains would be better. We don't know until someone measures the consumption of the motor alone. Belt drives can have quite high loss without load (around 3-4% maximum), but under load it usually outperforms the chaindrive. I don't know exactly why this is the case, but it might have someth...

Re: Sur-Ron - Belt upgrade KIT

Extra belt will be around 120USD.
The short belt is already installed on the bike so you dont need that.

Re: Stealth FUTR owners builds and pics

That's a neat way of tackling the cell gluing Allex, and one I hadn't thought of. Thanks for the tip...maybe that will save me a heap of time and make this more worthwhile in future. The only catch is no short protection between parallel groups. Maybe a double heatshrink on each cell would fix that...

Re: E-S Stealth Electric Bike Owners

Could you repeat that, a mid drive was riding by, and it drowned out what you were saying. :( :D I do like those controllers though. Now when you mention it: Here is what I have been working on, when replacing the chain to a belt - you notice one important thing! See if you can hear that! All I can...

You will be very surprised how loud your bike actually was once you try out modern sine-wave controllers.

Re: E-S Stealth Electric Bike Owners

Your Controller is now the bottleneck in the system, battery can prolly give you more amps but the controller will hardly demand more than those 70
Time for a new controller buddy?

Re: Sur-Ron - New Mid drive Bike

I really don't care if it last one summer or four. I am after silence and buying a new belt is not a big deal for me. Having not to tension it every 10 chargers, and lubing it every charge and also have a cleaner bike and MUCH more silent bike is worth so much more to me. My riding style is exactly ...
