Hello there! I'm really intrigued/interested by the new Frey CC bike, which looks to be a great commuter/city bike option with an excellent combination of hardware/components, etc. I'm fine with the price of the bike but it looks like it's a whopping $800 to ship to the U.S.! :shock: Do any of...

Hello! I have a bike with a rear hub motor, which I had been controlling with a half-twist throttle. That's more of a "manual" approach than I'd like -- and it's uncomfortable for longer rides. So I recently bought and installed the following items from Grin: (1) a PAS (cadence) sensor, (2) a...

Hello! I have a Surly Big Dummy cargo bike with Xtracycle bags and a BMC rear hub motor. I recently bought a rectangular battery pack for it that's 324mm x 140mm x 80mm. I'm trying to figure out the best way to mount or house it and wanted to get ideas from the community. For now, I've placed...

Hello! I'm looking to buy a battery pack for an ebike -- likely something in the 48V 14Ah range. I'm wary of just searching by price, since I don't want to get an inexpensive battery that's poorly made, doesn't work, etc. Can folks recommend a few/handful of battery pack suppliers that are...

yeah, sorry, my question was quite poorly worded. maybe this will help. in thinking about it further, the "feel" i'm looking for is that i'd like to be able to pedal at a given/constant cadence but have my pedaling effort not exceed a certain maximum. the analogy for a non-motorized bike...

hi there - not 100% sure this is the right place to post this question -- happy to receive a re-direct if appropriate. :) i've been using a throttle-controlled ebike for 2-3 years now and have been pretty happy with the experience for the most part. but since my goal is to use the motor...

Hi there - I posted an inquiry several months ago about this and was wondering if there might have been any developments in the meantime. Basically, I'm interested in putting together an ebike with a torque-sensing mechanism that'll modulate the power to a hub motor so I can limit the maximum...

oh man...i'm getting a bad feeling about this based on all of the negative comments i'm hearing about their BMSs. :| the wiring was labeled in a confusing manner and so i inadvertently connected my motor controller to the charge cable on the bms instead of the discharge cable. at least i...

yikes! didn't know i had so many things to worry about. my whole purpose of getting a pre-built system instead of putting one together myself was to avoid all of these things. i'd been trying to get a pack custom made by cellman, actually, but ended up switching to evassemble because cellman...

my mistake for not making my question more clear...apologies. my question is simple, really. for now, i'm planning to use the same wiring they supplied but just swap out the old (nonfunctional) bms with the new one. so the question is just this: does it matter what order i disconnect or...

hi there - long story short, i bought a battery system consisting of two separate battery packs and one capacitor bms. the bms failed so i need to swap out the old one with a new one (for now i'm going to use the existing wiring). does it matter what order i disconnect and/or reconnect the...

this may be an obvious question, but instead of trying to adapt my speed-based controller to use with a torque sensor, is there some place i can buy a controller that is designed to be used with a torque sensor (i.e., that has a torque sensor input)? i should add that i'm really wanting a...

hi folks - i have a throttle-based hub motor ebike, with which i'm happy. i'd like to buy another ebike for my wife to use. she doesn't want to deal with throttle control and wants something more automated. after a bunch of research, it seems that kalkhoff and bionx might be the two best...

okay, i think i'm willing to go the lipo route. but, i'm not particularly handy in terms of wiring, soldering, attaching connectors, etc. is there a vendor (or individual) who, in exchange for a reasonable fee, could build the battery system for me? i'd rather pay someone who's knowledgeable...

thanks, dogman, that's helpful. so if i'm interested in a simple (though perhaps more expensive) 48v15aH system, would i buy 6 of the 6s5aH lipo batteries, put 2 of them in series to create a 12s5aH subpack and then put 3 of those 12s5aH subpacks in parallel to create a 12s15aH final pack...
