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.

Battery ordered: 72v 38ah With 150A BMS eon lithium ICR21700 cells, $1K :shock: Have a link to this vendor? M He is pretty well known on FB ebikes sites. Works for m. https://www.facebook.com/marketplace/item/382337392644344/?referralSurface=messenger_lightspeed_banner&referralCode=messenger_ba...

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

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...

That worked very well
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!

Pictured below, here is another Batec Electric Series #1 model which happens to also have been downgraded to the Australian standard 10km/h maximum speed limit!!! This this particular model was originally advertised as traveling a maximum 20km/h European speed limit prior to then being shipped to A...

Up to 6km/h - 1up, 2,3,4 down Up to 10km/h - 2up, 1,3,4 down Up to 18km/h - 3 up, 1,2,4 down Up to 20km/h - 4 up, 1,2,3 down Great username :D Are there no other combinations that affect the speed like: 1 and 2 up, 3 and 4 down 3 and 4 up, 1 and 2 down 1 and 3 up, 2 and 4 down 2 and 4 up, 1 and 3 d...

Wow, where do you find the time to do so much work in a few days? Great work again!

Great bike to convert. I'll follow your build. Good luck and have fun

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...

Nice work
That's going to be a very nice EV conversion!

Wow
Great conversion! And serious power

Nice basis for a serious EV conversion!
What EV components will you be using?

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...

Hope you have a hefty torque arm for the motor

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

That will be a very interesting budget build
Especially using the Honda IMA motor. Good luck and enjoy building, I'll be following your updates on this.

Beautiful work

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 ...

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...

I highly doubt the conversion from ICE (Internal Combustion Engine) to electric propulsion will only cost €150,- to test and register. 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...

That's more than doable, but I searched for my country the estimated amount is 1500 euros. So that is a lot, but then it's licensed as a E-scooter so maybe if I do it as an E-bike that is cheaper Is that including the EMS/EMI (Electro Magnetic Susceptibility/Interference) testing? Or "just&quo...

Ahh I got you! Than I think 48v is enough for me because I live in a small village with no stopping signs and nothing remotely close to hills. So I think I will go for a 48v battery with a higher discharge rate, because I want some torque. Why not buy the motor with the controller that is matched f...

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...
