    Ninja 250 "Clone" Made in China

    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...

    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...

    Qulbix 76R build

    I haven't seen many reviews on this bms but have had my eyes on it for a while. Might be worth checking to see if it would work for your needs . https://endless-sphere.com/forums/viewtopic.php?t=85357

    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"...

    Bitcoins

    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. There were 5 drops of 30% or more for bitcoin in 2017. All of these were followed by an even more bullish...

    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.

    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?

    Qulbix Q76R Frame Kits & Complete Bikes PRE-ORDER

    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.

    Help me choosing a 10kW continuous system

    Byte - I would check out this combo for a sevcon and me1302, it should fit your requirements for both power and price https://endless-sphere.com/forums/viewtopic.php?f=9&t=91659&p=1336347&hilit=Sevcon+me1302#p1336347 *edit* I realized the link above doesn't have a price posted. Pretty sure I...

    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...

    South America mid drive e-moto

    Cool video! Looks like a nice build. I'd be curious to see some pictures of your bike when you are able to take some. I would be careful with those zoom forks...especially jumping. For street riding they are probably alright but I wouldn't trust them for much else. I have a friend that has...

    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...

    Ebike Hub Motor overheating cooling solution - HUBSINK OFFICIAL THREAD

    To anyone looking for high power but worry about heat the combination of Sketch's hubsinks with FF is sure to solve that problem. My bike running a QS 205 & Sabvoton combo on 20s at 150a battery came alive after this upgrade. Previously when riding hard my motor temperature would often...

    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...

    Here are a couple pics of farfle's awesome project. I'm friends with him on facebook so got the pics from there. Hopefully this is alright with him that I shared them here!

    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.

    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...

    Light weight full suspension mountainbike --WITH VIDEO--

    Very cool as always ;). Sorry to hear about the mishap with the connectors. Bullet? If the fit is loose I try to slightly bend the male connector's prongs outwards a bit. And although some think it is tacky or unprofessional gorilla tape has become a huge help with these bikes for me. For...

    Electric Supermoto - QS 205 v3 - Sabvoton 72v 150a

    Bit of an update...rebuilt the bike after a hit and run late last year. New frame, fork and front wheel. Brakes upgraded to shimano saint m820. Upgraded battery to 20s30ah with onboard 900w bulk charger. Also i'm waiting on a sabvoton 72v 150a. Will update with more pictures and video when...

    Vector bike and frame owners.

    I don't think I would trust zip ties to hold a person. Might not look the best but I've used C-clamps on my rear swing arm as rear pegs and it has held up for over 3000 miles (100lb passenger weight). An added bonus is that the motor phase and hall wires are better protected in the event the...

    Mobipus Controllers

    Is there anything in between these two controllers? I'm very interested in the 72200 but am slightly disappointed it isn't more power as my current controller is already 14-15kw peak. At the same time it is hard to justify the extra expense for a 600a controller if I only need 3-400 max

    trackbike codename NODLEHS

    Sprocket size shouldn't be a problem. Here is an example that uses this motor. I don't know offhand but it looks like a low kV motor based on the gearing. Almost like a hub (it is an outrunner) but mid drive. Cool project and nice modeling! I look forward to seeing this progress.
