Re: Vespa PX125 (Large Frame) Electric Conversion.

That looks indeed much better than the photo I posted from his own ad on FB. I think he should update those photo's with these you posted of your battery pack.

Re: Emax s110 scooter with 60v lithium batterie

That is really a very bad soldered connection especially the negative wire :shock:
Why not solder them both directly into the connector?

Re: emax s 110 with 60v lithium battery

BMS (Battery Management System) that is protecting the battery for too much current draw? If the battery you are now using is for a maximum power of 2300W and you try to extract 4000W then the current is too high and the BMS will protect the cells by shutting down. You'll have to program the control...

Gun metal gray should suit the bike well. But if you leave them as they turned out now is also great. Much better than the gold!

Re: Electric Roadster Motorbike

Although that controller is so large it will probably never overheat without burning out the motor first, why not rotate the controller so that the aluminium cooling plate is facing the front of the bike and thus the air flow when riding? You could weld tabs/strips to the front down tube to mount th...

Re: Electric Roadster Motorbike

I agree that, when using regenerative braking, a clamping torque plate or arm is a better solution. But that doesn't mean that the plate you are currently using that came with the motor is not strong enough. Just that the little play between the hole in the plate and the shape of the axle will cause...

You're kidding, right? There is a torque plate and the whole steel swing arm is a torque arm :wink:

Re: A rookies first build

You're welcome. Changing a structural part of the frame and/or swapping in a different engine/motor is indeed altering it so much that you would need to get it tested and have the changes registered. And that is not so much a problem with the police but more in case of an accident to still being ins...

I think the best and most cost effective way to "build" an electric moped to your liking is by modifying an existing electric vehicle that has already got a licence plate. To first learn about modifying you could buy a second hand one with low mileage and lead acid batteries that has been ...

Re: I made an electric wheelchair from a scooter

I'll type it again: use a GEARED hub motor in a small wheel! That way you'll have all the torque you need. And when overvolting it you'll even get enough speed. You can weld or glue the internal clutch so you'll be able to have regen braking and reverse. A Q128H in a 12" or 14" kids/pitbik...

What a very nice look and finish of those aluminium parts. Great result! As for the fork tubes you could probably seal them of with temporary plugs glued in/on top and bottom using silicone sealant/glue. Making them "watertight" when submerging them in PVC tubes. I hope you'll get the same...

Yes for changing the ICE to another ICE or changes to the frame where just some paperwork and a visual check are needed. But again the EMS/EMI testing and certificat...

Re: slow ebike... 80 volts ebike going 30mph? why so slow

It says in the advert of the link you posted that the controller has "three speed reversing" so it seems to have a 3-speed switch that needs to be installed. If you don't have such a switch installed the controller might be in "1st" (low) speed and you need to connect a compatibl...
