Re: Since the Sur-ron dirt bike was such a success anyone have info on their motorcycle

I would be surprised if they've sold that many to be honest. The bike is unsuitable for an advanced user, fairly expensive for a newcomer or casual user especially compared to gas bikes and where do you ride it? It's about as streetable as an actual dirtbike. If you were a rich casual rider with ac...

Re: Taiga TS2 electric snowmobile

Hm I wouldn't mind a quiet electric snowmobile, however I am unsure if Taiga TS2 is the solution. Frankly I don't think they pack enough batteries to make for a usable ride. A snowmobile unlike a road driven vehicle is already from the get go battling the odds, lots of rolling resistance in the driv...

Re: Gas Gas Trials bike conversion

Thing to keep in mind when ordering from china is the shipping time, anywhere between 4-12 and even 16-18 weeks are normal. Some shipping agencies will take various bulk cargo for cheap shipping rates, but they collect goods until a container is fully loaded before they place the container onto a sh...

Re: Vector e-bike Frame 599$ /Adaptto/Parts WORLDWIDE

The video is that the one Artur made like a in november? 4 months later things should have improved from factory, I think Sur Ron did motor upgrade already maybe even some other things. Artur was gonna get the Sur Ron road legal, and that is a big issue to avoid legal problems because the bike don't...

Re: Vector e-bike Frame 599$ /Adaptto/Parts WORLDWIDE

Artur, how goes the process of starting to sell Sur Ron in EU? Did you manage to get the Sur Ron road legal as a 45 km/h moped or possible even A1?

I remember you talked about this before christmas but since then I have not seen anything more. Let us know how things goes with the Sur Ron for EU.

Re: Sur-Ron - New Mid drive Bike

I was thinking. Since there is a brake/throttle interface and there is some kind of control over power delivery, would it be possible to program a clutch type action for trials activities. Maybe a couple different ways that the motor ramps up after releasing brake? I'm a total newb when it comes to...

Re: Definitive Tests on the Heating and Cooling of Hub Motors

Browsing via mobile phone so hard to see the graphs clearly. Core to shell seems to be the bottleneck. Would adding yet another hubsink side by side with the first one make a worthwhile difference?

55H? Not 50H? 55H. See: https://www.qsmotor.com/product/4000w-car-motor/ Qs 205 hubs are sold by la bikes in your continent. Ok thanks I will check them out. That motor is for car use. Are you maybe building a single sided swing arm? If so I wouldn't mind pics or back of the napkin drawing.

Re: 45KW + Electric Dirt Bike Best Motor, Batteries, Controller

Similar project, sort of. His is turned into a supermoto. But he could have kept it mx style. Make sure you watch the video #2 and #3 by the same poster. As you can see more details of what it takes to get a reliable build in the 50 HP +.

Re: Neumotor 8057/75 middrive project, belt drive, adding halls, 10kW+

As you can see the hall signals have properly shape, and the accuracy is not bad. There are small variations in signals length which is probably cuased by not 100% identical distances between the magnets. But still not bad for 3D printed parts, and as the no load constumption is quite good i can li...

That dirt road is like a highway, just run your truck into the woods for a rescue mission. If vehicles are not allowed try make the run at early hours or late. Yeah a mile of pushing that thing uphill sure will take its toll. Don't know why I figured your bike was stranded close to the truck, I did ...

Sorry to hear about the melt down. If you got a mx bike or a quad you can tow it out of the woods, or can you get your hands on a 4wd car that will make it to your bike? If not, you got to do it old skool. Muscle power, and ropes and pulleys to aid up the hills. If there ain't decent trees or rocks ...

Re: Sur-Ron - New Mid drive Bike from China

Yeah it didn't seem that the 450 rider was working really hard, nor revving hard either out of bends and corners. On the flats when he crack open the throttle he pulls rapidly away from the Sur Ron, then 450 riders play it safe in each bend. I think in all honesty that for the Sur Ron to really matc...

Yeah I see what you mean, and I am partly agreeing.

Thats kind of why I was so bummed when mobipus went OEM only. His controllers seemed to be the perfect fit for hi power, great features and decent pricing. His 72 200 controller was able to push 12-14 kw I've heard, for really short burst closer to 20 kw. With lots of great features. In my eyes mobi...

Re: Sur-Ron - New Mid drive Bike from China

don't know if it got freewheel, I would assume it does. But that is not the major issue with the pedal kit.

Re: Sur-Ron - New Mid drive Bike from China

Does the pedal kit already have the potential to work just as a fake pedal setup? I assume it has a freewheel mechanism to let the bike move faster than you can pedal, so can the freewheel be disconnected from the rest of the kit, leaving pedals that turn without doing anything else? Better still w...
