Re: Sur-Ron - New Mid drive Bike

Has anyone measured the power output of the USB-plug from th Sur Ron? It says 5V 2,4A on it.
If so it would be enough to power an additional 10W LED on the handlebar without mounting the associated 1S3P batterybox.

Re: Sur-Ron - New Mid drive Bike

I'm guessing I can just bump to 110 and see if it starts cutting out but my tiny garden isn't safe to push it that high :lol: Pulling temporarily more than the "not tripping" 90A is possible. I tested my stock battery with short bursts up to 120A. If this load is within 5-6 seconds and th...

Re: Sur-Ron - New Mid drive Bike

@Offroader Is this how you drive around every day or was it just a picture after installation of the nucular (not nuclear :D ) controller? I know it's a matter of taste but having the cables sticking out like this ruins the whole (closed) look of the bike in my opinion. And of course the protection ...

Re: Sur-Ron - New Mid drive Bike

I wonder if maybe thermal pasting the Nuc 24f case to the plate inside the stock housing would help? The FETs in the Nuc are sitting on the two sidewalls so I guess this wouldn't help much. With the stock battery I had no problems at all with heat. But with peaks of nearly 21kw the 24F starts sweat...

Re: Sur-Ron - New Mid drive Bike

I saw someone who mounted their 24f inside the stock sur ron controller heatsink. I might have to buy a dud controller to try that, I love the look of the stock controller. I have done that too because of the looks. The "donator"-Controller had all his connectors cut directly after exitin...

Did you have to pay extra taxes when importing the Nucular 12F controller?
No, both of the nucular controllers 12F and 24F came without any extra payment whatsoever to my adress in Germany.

Re: Sur-Ron - New Mid drive Bike

you can pull slightly more than 120A from the stock battery Sadly thats not the case anymore. I got a late 2019 model and get BMS cuts if the battery amps get higher than 95A constant. Pulling that less than 5 seconds and you're good but I don't want to risk a forced restart of the system. You woul...

Re: Rohloff: torque limit issues

I think you are mixing two things here: 1. Torque 2. Radial force The thing you feel when accelerating is radial force transfered from the wheel to the ground. Torque on the other hand is the force acting in the middle of the wheel. And as you know Torque is the product of Force times lever length ....

I'm not good at expressing myself with pictures so I will try to explain the tensioner I propose better. It would sit between the swingarm pivot and the motor sprocket and be mounted on the swingarm so that as the suspension is compressed it comes into contact with the lower chain to take up the sl...

Re: Need help with my big wheel scooter project

Do you think 3V 500W hub motor on 16 inch wheel can go 30km/h or more on flat, and 15km/h on medium climb? Of course if paired with the right controller. If i were in your place I would either buy a hub kit with controller (cheap) OR the hub seperate and a VESC (full programmable controller for abo...

Re: Need help with my big wheel scooter project

The 6384 is definitely capable of delivering you desired speed BUT you will have to watch the motor temperatur on longer uphill climbs. I built a scooter with a 6374 170kv and a longboard with a 6384 170kv and both were geared to around 45-50km/h with good acceleration. They are small but very power...

If you got some longer bolts that attach the frame to the battery case, you should be able to get some chinese pit bike foot pegs from ebay or amazon. May have to be a little creative on the mount to the frame but they would be way grippier especially when it gets muddy or wet. You are right I defi...

As you saw in the last video the nucular controller finally arrived.

So I decided to mo...
