Re: My Electric Motorbike

In regards to the slow acceleration...you can try adjusting the settings for acceleration time under the throttle menu. Keep this in mind (from the sabvoton manual): The less the “acceleration time” or “deceleration time” is, the faster the throttle will response ,(It is forbidden that the time set ...

Re: Drag 2WD ATV

You could wire up the pack as two separate 24s blocks connected in series (48s) when you are running and parallel (24s) when charging. That way you can still use the power supply you already have. Just make 2 "Y" adapters - one for charging and 1 for running. I've done something similar on smaller s...

Re: Sabvoton worse than cheap Chinese controller?

I know what you mean...I've used a few 36fet greentime controllers. 4110 and 4115 versions. Peaking wattage was between 15-20kw depending on battery configuration. 32s on a 90lb bike is no joke. It would power wheelie through 40mph if you weren't leaning forward. And this was with a 6" extended swin...

For people outside the crypto world a 30% drop might seem like the end or definitely a turn for the worst...but for people that have been involved for a while this is really nothing new.

Re: Bitcoins

I would highly recommend anyone with a decent amount of bitcoin to get a hardware wallet and get it off the exchange. I use a Trezor and it is pretty easy to set up and transfer to. Now I don't have to worry about my coins disappearing from an exchange or my account getting closed or locked.

Re: South America mid drive e-moto

Thanks for the pictures! Nice work! Glad to see you have upgraded your fork, I've used an old Marzocchi 888 and the 380. Much better than Zoom. It also appears that you have potted your BMS? Good idea, can't say I've seen anyone else do this. What did you use?

Your chain might be too loose? You could try taking out a few links to increase tension and to help prevent the chain from jumping around. Nice build! I like the all black.

Re: Help me choosing a 10kW continuous system

Sabvoton has a 36fet controller that is capable of 200a battery and 450a phase. It might be possible to get it unlocked for even more since the 24fet can do 200a unlocked. Although this is only 90v or 20s max it is probably the best controller available for a hub that I know of. https://m.aliexpress...

For street riding they are probably alright but I wouldn't trust them for much else. I have a friend that has them on h...

Re: Cheapest e-components for 55mph?

In my opinion a mxus 3k will be under powered for what you are asking. Having used both the mxus 3k and a QS 205 v3 I can definitively say the QS is far superior. If you go with a hub and are set on no rear brake maybe regen would be a good option? I would still agree with the other comments that no...

To anyone looking for high power but worry about heat the combination of Sketch's hubsinks with FF is sure to solve that problem.

Re: 100+ Miles of Fun per Charge: 5.1kWh batt, 20kw capable

Aero shouldn't even be a concern for speeds between 20-25mph. You might be able to gain 10% range with a fairing but clearly this isn't a concern for most people as very few examples of fairings for e bikes exist. Obviously a trike will have much less drag compared to a bike because of the frontal a...

Re: 72 vott e-bike

I've heard that controller is actually only 150a battery...the 600a is phase. If you want a true 600a controller check out the mobipus 72600. Otherwise a mobipus 72200 or either Sabvoton 72150 or 96100 should be enough.

Re: MOTOR PORN !! EMRAX 228 teardown !!

macribs - afaik FF will only work on hubs. FF bridges the air gap between the stator and the magnets. Emrax is an axial motor not radial like a hub so I don't think it would work the same. Although you probably could put FF in the emrax it would probably spin off because the magnets are mounted vert...
