Re: Sur-Ron - New Mid drive Bike

This is a post about group modification. http://bbs.sur-ron.com/#/t/118 I think I got 50% of the article because google translation, but... seems a bit overengineered when you can use this https://www.amazon.com/gp/product/B007Y5GMOM (plus: I found that having the handlebar on this kind of stem can...

Re: Sur-Ron - New Mid drive Bike

Does anyone find the stock sur-ron handlebar doesn't feel right when holding it? It seems it puts your wrists in an odd position or something. I'm not talking about the low height. The reason I notice this is that I was using a 3" aftermarket deity handlebar and that felt very good. Then I put back...

Re: Sur-Ron - New Mid drive Bike

Took my bike into Manhattan for the first time. I was worried about bringing this beast of a bike on my local ferry boat that I need to take in order to get into Manhattan. They do allow bikes and electric bikes, but the Sur-Ron is more like a motorcycle than an electric bicycle. Luckily they didn'...

What rear tire is that? Looks awesome.
It does look nice. How does it handle and how does the rear suspension handle with the increased weight?

Was it worth to go with something so big and heavy over the stock tire?
My advice: enjoy the performance of big teeth and ignore the weight lag

Re: Sur-Ron - New Mid drive Bike

Did some testing with the Vesc 75/300 on my streetlegal Version. Works fine with 14S 16ah Lipos (will be 32ah when finished) at the moment although the Vesc can handle 16S. Regen is now possible and because of FOC the motor is more quiet. App showed me 8,5kw peak at 300phaseamps. Not sure if these ...

Share with you Do you have a picture of the front of the bike with it installed. I do know lights make riding at night in the woods like almost riding in the day. The only issue is you will come up upon lots of spider webs at night and you will see them also as the lights reflect off of them. https...

Re: Sur-Ron - New Mid drive Bike

Any idea why a Sur Ron won't turn on? I went to show my bike to a friend just now. Bike was just sitting in my garage and has been out for a total of 1 real ride. Turned on the key and the headlight turned on just like usual. Sat on the bike and went to twist the throttle a touch and nothing happen...
