Just like the subject line says. Looking for a 55+mph 50+mile and 350+ lb carrying capacity maxi scoot. I see a lot of "maybe soons" out there. But without going to a motorcycle like (somewhat expensive) Zero or the (really expensive) BMW there just is not a lot of 2-wheelers out there for...

I considered this. They are also selling them on Amazon. However I have not been able to get a response from them about if this is only 36V as listed, or can also run at 48V. At the moment I have (4) 6S 10Ah 22.2V lipo from the recent HK sale. I probably should have went for the 3 or 4S combos...

Thank you all, but we may be digressing a bit. As controllers are easily replaced why not concentrate on the motor itself? Is the BPM2 worth the extra cost?

Unfortunately that is about all that BMS lists on their website for information. I am inferring from the information they list that for the Q128 they are using their S-KU95 and for the BPM2 the S-KU125. I plan on using both the PAS and throttle. S-KU95...

One last question for everyone here. Planning on pulling the trigger on my conversion kit order from BMS Battery and cannot decide between the two. This is for a front-wheel application. I see Q128 comes with a 9 mosfet 450W controller and the BPM2 a 12 mosfet controller. Also the Q128 is listed...

I laughed at that. I am one of the sacrilegious ones who lubes his motorcycle chain . . with WD40 :shock: . A spray and wipe every 100 miles or so.

Soldering I know. Wiring I know. But the ebike tech? Still a newbie. I will take a look at the MXUS. Mainly theft. It is quite hard in my area to keep what is yours, yours. I have had everything from lawn mowers to 20oz bottles of soda stolen (thank you thief for the $400 to replace that car...

Ah, gears. Good point. They are plastic from what I have seen. The good news is if I decide to buy a Q128 front for the kickbike and a Q128C for the Schwinn the replacement parts will be common. I assume you mean by buying an entire motor I can switch out the gears and stator as a unit if...

Thank you for the recommendations. I am assuming the square-wave is the more generic SLA scooter/motorcycle/ebike type? The Q128C rear is now available built-up in two speeds. https://bmsbattery.com/ebike-kit/769-q128c-135mm-500w-rear-driving-ebike-hub-motor-wheel-ebike-kit.html I was mainly...

After some constructive comments on my planned build by motomech I am looking at using a built-wheel Q128C (hopefully as part of a conversion kit). Is BMS Battery the only source for such motors? First the wheels are not offered in a conversion kit. Second I am not thrilled on what I have been...

I know the CLG-150-48A (150W) will go to 56V as that is what I am considering on my 12S build. Looks like the HLG-320H-48A goes to 52V? http://www.mouser.com/ds/2/260/HLG-320H-spec-226092.pdf

I plan on running my batteries between 3.7-4.05V. Probably 40% capacity to actually use? Combined with the fact this will be used for commuting I would like to (eventually) have at least enough capacity for one "oops, I forgot to charge it" 1.5 round trips (home-work-home-work). Not a priority...

Well, I already have a pretty decent feel for everything but figuring out about the controllers, but here I go. Desired max speed on level ground: >18mph. This is a commuter and "get healthy" build, not a speed machine. Desired max range at what cruising speed. 18-20 miles at anything over...

Interesting. I guess that makes sense as the cheap controllers are probably designed for use with SLA batteries instead of LIPO. I will take a look at your posts. I actually have (4) 10Ah 6S Multistar LIPOs on order. My intention is to create a 44.4V 20Ah pack. 2 parallel, then 2 series for ease...

Sorry if this has been discussed before. Is there a decent guide covering everything a person should/needs to know on the cookie-cutter generic ebike/scooter/moto motor controllers? Especially identifying and repairing common problems, common modifications/upgrades and wiring diagrams? For...
