Re: Sur-Ron - New Mid drive Bike

One thing that happened today is that my shoe lace got caught in the chain and I had to back the back up to get it unstuck. I wasn't going too fast.

I wonder what would happen if you get a shoe lace stuck in the chain at speed? Will it just rip your shoe lace off and that is it or could it be worse?

Re: Sur-Ron - New Mid drive Bike

Very nice, just climbed the full 5 flights of stairs, or 100 steps in total, without stopping or touching the ground. Something I always dreamed about doing but never could with a hub drive bike. These steps don't just go straight up, that would be easy, you have to make a very sharp turn to get to ...

Re: Sur-Ron - New Mid drive Bike

Yes I think you are right it is probably similar to the converter you posted. Come to think of it since I removed the halls module I have the room to mount another DC/DC converter in that location. That was actually the issue I was having was that I couldn't find any location to mount something. I d...

Re: Sur-Ron - New Mid drive Bike

Would anyone happen to know what that silver device I circled in the picture is? It has 3 wires going to it, Black/Green/Red wire. Is that the DC/DC converter? If it is, does anyone know how many amps it is rated for? Yes, that's the dc-dc converter. I couldn't find any marking on mine, but didn't ...

Re: Sur-Ron - New Mid drive Bike

Thumb throttles r weaksauce. You can't ride trials with em which is the ultimate test. That was figured out in the 70s in france and austria. prove me wrong and post a video hopping up on a boulder What I believe is that preference comes down to what you are used to, and most people don't allow eno...

Re: Sur-Ron - New Mid drive Bike

Yuck get that thing off my bike. No reason to use a steel cable that just converts the signal to halls for the controller and that probably adds resistance and play into your throttle control. Good point. Think something like this would work? https://amzn.to/2PAn5XY Yes basically any ebike throttle...

Re: Sur-Ron - New Mid drive Bike

Swapped out the Twist and put in the Thumb throttle. :bigthumb: It went smoothly, the wires were color coded correctly, (Red = +5 / Green = Signal / Black = - ) I removed the twist throttle, cable, and hall sensor module. Took it for a 5 minute ride tonight and it was just perfect and the throttle c...

Re: Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

No wonder why you are having difficulty fitting that thing, it is huge.

The Max-E 24S BMS is much smaller.

What controller are you using for your build?

Re: Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

if you get a chance maybe you can post a picture of the BMS. I'm curious to see it. If worse comes to worse you can mount it under the seat or in back of the frame. I'm not sure what seat you will use but you can see all the crap I have under my seat. You can also mount it behind the rear shock. Act...

Re: Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

I would put it under the charge port, I considered that option as well. Yes you are going to most likely have to deal with the wires to the BMS to make it fit. Not that big of a deal, will take some hours of even soldering on new wires but you may have a neater setup. I would use thin wire, like 24 ...

Re: Sur-Ron - New Mid drive Bike

Yes the bike is loud for sure. Everybody looks or turns their head when you drive by them. I guess this is one of the draw backs for a mid-drive or maybe a positive if you want it to sound like a motorcycle.

Re: Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

I had that same reinforcement on my frame, my Max-E BMS just fit through those holes as it was rectangular in shape. If you are using another BMS it may not fit. What I planned on doing was wrapping the BMS in foam and just push it through the hole. Then after I run the wires through, I would squish...

Re: Sur-Ron - New Mid drive Bike

I got the Saint on Black Friday for -20%, the difference was not that big anymore for the Zee. In addition, I already have a Zee on my other bike and wanted to test for myself how the difference is from the Saint to Zee. I had to shorten the hoses for front and back. If you take care that nothing l...

Re: Sur-Ron - New Mid drive Bike

I checked my chain tension today and after 50 miles there was a lot of slack. Maybe about 1.5". When basing the correct tension off this link https://electricbike.com/forum/forum/knowledge-base/surron/55116-sur-ron-documentation-specs-unboxing-and-initial-setup recommends between .5" and .75".

Re: Sur-Ron - New Mid drive Bike

Brakes: I had the MT5 in front to test (I had borrowed) and that worked great. The braking force was great and a huge difference to the original brake. However, I have now got a Shimano Saint because I like the shorter levers. The braking force is even higher :twisted: Derb, forgot to ask you, any ...

Re: Sur-Ron - New Mid drive Bike

Derb, last time I used my bike I noticed an odd noise but wasn't sure if it always made that noise, I wonder now if it could be the chain loosening. I think it made the noise mostly when I left off the throttle and coasted. I guess I have to keep my eye on the chain. Without Regen you will eat bicyc...

Re: Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

I'm copying your battery build, except I will use Samsung 30q and I will parallel connect them.. So it will be difficult to fit a bms anywhere inside the frame. Also I cant find a smart bms that would fit width wise. I know the MAX-E BMS fits in this location as I put it in there to see if it would...

Re: Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

I never mounted it but it depends on how much room you have in the battery compartment. I don't have enough room in the battery compartment so I was going to put it inside that space at the very bottom of the bike through the hole.

Have any of you guys cut down the width of the handlebars? They feel kind of wide and I'm not sure if I should cut it down a little bit. They are 3" wider than my other ebike.

Re: Sur-Ron - New Mid drive Bike

Congrats on your new bike, I am sure you eventually will squeeze more power from this, modding or tweaking. For riding in the cold I find there is only one solution on any bikes or even snowmobiles. Handlebar "bark busters". It deflect the cold wind away form your hands. Big win. Btw, on the subjec...

Re: Sur-Ron - New Mid drive Bike

Nice video on the stairs :thumb: I think the Sur-ron motor and drive train can easily handle 10+kW. The battery is the limiting factor. Sooner or later they will come out with better performing cells and a battery rebuild will be pretty attractive. Stuffing the battery housing full of Lipo would be...

Re: Sur-Ron - New Mid drive Bike

I doubt that. It was self built. Quilbix frames are excellent quality too. There is a lot to be said for a silent hub setup. Loads more power than Sur-ron. Perhaps offroader can chime in. My Qulbix was ordered with just the frame and I built everything else. My Qulbix does have a much larger pack a...

Re: Sur-Ron - New Mid drive Bike

WOW, just amazing. This thing is an incredible machine.

I'm am starting to get much better control with the twist so maybe I'll stick with it a l...
