    I would just stick with 48v for now

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Ah Ah, cool, wish I knew they made a 24x2.6, I just bought a 24 x 2.35 pickup. For cargobike with the a DM01 mid drive (Now stopped working). That’s cool if you think you can run smaller wheels on a 29er full sus, I though pedal struck and bottom bracket clearance might be an issue, but prob...

    Cool, so changes/improvements continue to be made. Good to know

    I’m looking at 26”. So that should help with hill climbing? Although as mentioned not so many full sus frames around with 26” wheels. One of the good things about hub motors to me seems to be ability to switch between bikes without much trouble, but on the other hand you’re restricted to the...

    My econo-e-bike

    That's quite an elaborate setup. Sorry if you already answered this elsewhere, but what speed do you get at the upper end? I saw somewhere you mentioned a plan to build a mid-drive, maybe BBSHD build, did you end up doing that? And why did you think about that considering you've already...

    UK gov' consultation to allow higher power ebikes and throttles

    This may be worth a new topic, what would be appropriate regulation for medium powered ~1kw ebikes? For public safety maybe ensuring bikes have a decent brake system (mandated disc brakes, with particular specs?). Certified batteries might go some way to making governments more comfortable...

    Nice, do you use specifically paired and balanced batteries? I have one 15ah battery which has terrible sag, and a 17.5ah. So it could be risky running them down to lower voltage. I thought this would combine the amps of two batteries, but not sure. It automatically shuts one battery off if it...

    User profiles (BBS02B, BBSHD) for BBS-FW (Daniel Nilsson's Open Source Firmware)

    Thanks for this. Is there a way to upload the profiles so you can just load them straight into the programming app? My 02 I got from a guy comes on way too strong too fast. It needs some fine tuning, people talk about getting a torque sensor like-feel - would like this smoothness with also high...

    UK gov' consultation to allow higher power ebikes and throttles

    I think this is in large part also a problem driven by infrastructure. Roads are not designed for bikes but for cars. Footpaths are not designed for Ebikes. There is not really a place for ebikes to ride. Therefore governments to try regulate high power Ebikes out of existence rather than...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Thanks, this makes it easier to know what people are using. As for batteries, is there a reason why people don’t use two pre made packs in parallel or series to get double the amps or volts? Eg two 36v packs to get a 72v system? Or two 52v to get higher amps? Hard to find ready made batteries...

    Overvolting BBS02

    Can amps be increased on BBS02b by fitting a BBSHD controller - will a HD controller fit the 02? The blot holes seem to line up. Considering using a Luna Ludi modded HD controller and firmware with 50a-60a capability. Edit: apparently it can be done. The HD controller can fit the 02. Do you...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I’m talking aggregate, across Ebikes and electric cars as a whole rather than on a per vehicle basis. Anyway probably still far more than double on oil alone, before considering battery materials etc

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I can’t help but feel that if a company like Tesla put a few of its engineers and designers to work on ebike motors and batteries they could come up with some significant advances. This motor seems to be pretty similar to what was being sold ten years ago. And the BBSHD is the same. Ebikes...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Got a link? And battery wise, where do you find batteries that can push higher amps? The reliable sellers I’m aware of top out at 50-60a for 52v batteries (which is probably enough but doesn’t leave much headroom)

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    I’ve got three mids, BBS01, BBS02 and the DM01 (torque sensing 160nm mid), but the DM01 packed it in and the others aren’t powerful enough for my main bike… I’m keen to get just one good bike, and trying to make the decision. I wouldn’t mind having one of each, M635 and Leafbike. But stock they...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    That’s about what I’d expect from a HD at 52v, ~37mph. Totally understand the perspective on the benefits of the Leaf bike but I’d need another advantage over the M635 to switch to a hub, like a bit higher top speed, to get motivated to switch to a hub

    How To, 50A BBSHD Controller Mod

    I’d be interested to know if you could do this with the new torque sensing BBSHD M635. At least the shunt mod but also higher voltage. Would prob make the torque sensing settings a bit complicated

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    What setup do you run to hit 59mph? I’m still leaning towards the torque sensing BBSHD M635, maybe shunt modded - it looks like with a standard 48v or 52v setup the top speed is pretty similar between BBSHD and Leafbike, so with the benefit of gears it makes sense to stay with BBSHD and have...

    Wow, sounds like you have some really cool bikes. I’d love velo with the rain here

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Do you guys run torque sensors with the Leaf? I definitely want to go more than 28mph. Currently can pedal meaningfully along with the DM01 at 67km/h on a slight decline. But that motor has given up. The hills I climb are not too steep when extended. Typically riding 10-35km on country roads. To...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Not technical or slow climbs, just up roads in the range. Sounds like the leaf could do the job. I saw you are looking at building a mid-drive though, @E-HP , is that why you are getting one?

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Can anyone speak to relative benefits of getting one of these rather than a BBSHD (torque sensing M635)? It seems that with enough power they can power up hills no problems. Probably can also go faster. I have to go up some longish and steep hills, but also want to go fast. Was planning on the...

    My econo-e-bike

    What is your top speed on this bike? It looks great. You seem to climb a lot of hills with it. Would you see any problem in going for this type of build over a BBSHD / M635 torque sensing BBSHD, with large hills as part of the regular terrain? Any advantages or disadvantages?

    2016 Salsa Marrakesh flat bar frameset, Bafang BBSHD & Luna Ludicrous V2, Shimano Alfine 8 IGH

    How does it ride? Do you top out for pedal cadence with plenty of speed left under throttle or PAS?

    Solid state batteries?

    Did anyone try this?
