    BBS02 throttle is only on/off (not smooth/proportional)

    I took the BBS02 for another test ride, this time on a really long and flat road. Turns out, the throttle is *not* binary, but the range where the throttle is proportional is really small. It's possible I have a lemon for a throttle, so I've ordered a couple alternatives. (I'm really hoping it's...

    BBS02B controller upgrade?

    Yup - that's more or less my take on the situation too. If you're new to ebikes, BBS02 will probably seem wonderful (because *anything* compared to nothing is probably great). I want to upgrade the controller, but so far I've not found any compelling alternatives. For an alternative to be...

    BBS02B controller upgrade?

    So if you buy a BBS02B your throttle is really just an on/off button, and apparently it's been this way for years. So is it possible to upgrade the controller to something that works correctly, without breaking the bank? These folks want $484, and they don't even mention the "B" version. This...

    BBS02 throttle is only on/off (not smooth/proportional)

    Thanks. I'll read that thread. If this cannot be fixed, Bafang's BBS02 is flawed in a serious way (but not fatally). Makes me wonder: Hasn't anyone at Bafang ever used a good ebike with a proper proportional throttle? How could they even ship units with obviously broken firmware like this? The...

    BBS02 throttle is only on/off (not smooth/proportional)

    I just installed a new BBS02B 750W 48V (850C display) into a hardtail mountain bike with 27.5 tires and a 8 speed cassette. I used this kit from Amazon: https://www.amazon.com/gp/product/B078YNVH9Q/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 Overall, it works well. I've used hub motors for...

    Super reliable commuter.

    Maybe I've just been lucky, but I've found the Aotema (formerly Wilderness Energy) front hub motors sold on ebay for almost nothing to be amazingly reliable: http://dallasebike.blogspot.com/2015/06/beater-e-bike-for-only-386-batteries.html If you are capable of replacing the sealed bearings...

    Electric bicycles and weight loss/lifestyle change

    In 2012-2013 I got very depressed and lost a bunch of weight. I basically was a ghost of my former self, and I could barely walk out the front door of my house without getting super tired. Part of my recovery was ebiking on the trails around Olympia, Washington. I would bicycle as far as I...

    CycleAnalyst direct plugin throttle latency

    I bumped all three settings to 99.99 and now the throttle latency is much more tolerable. (Silly me, I didn't realize you could bump the settings this high.) The latency is still higher than my old Wilderness Energy setup, but it's not bad.

    CycleAnalyst direct plugin throttle latency

    Also, all 3 throttle ramp settings are set to 7.99 volts/sec., which seems to be the limit.

    CycleAnalyst direct plugin throttle latency

    I switched my main commuting bike from my old Wilderness Energy brushless controller to a CA-DP with a C3620-NC controller. I have the throttle directly wired to the Cycle Analyst (CA), and the CA controls the controller's throttle. Everything works great, except my throttle is now delayed by...

    Ebiking in Dallas

    I've started a little blog about getting around Dallas and the surrounding suburbs on ebikes: http://dallasebike.blogspot.com/ I've ebiked thousands of miles through the DFW metroplex over the years, and I commute to work every day on an ebike. Sadly, I have yet to see a single ebike anywhere...

    bearing replacement on a Wilderness Energy BL36 front motor

    Thanks for all the suggestions. I removed and replaced the bearings and put the motor back together successfully. I used basic hand tools and this bearing removal set to get the bearings out: Wheel Bearing Remover Separator Extractor Puller Tool - Pit Posse...

    bearing replacement on a Wilderness Energy BL36 front motor

    Thanks dogman, I'll try that and report back what happens.

    bearing replacement on a Wilderness Energy BL36 front motor

    Hi all, I originally bought this front brushless hub motor kit (BL36 - 36V 20A) from Bernson EV (now defunct). I believe it was made by Wilderness Energy (also gone). I've put many thousands of miles on this amazing little hub motor, commuting to work or the train, with no problems until now...

    NiFE batteries from BeUtilityFree

    I've been told by the importer (BeUtilityFree) that the recent earthquakes in China have slowed down the electrolyte shipments. I'm supposed to receive another shipment next week. The large voltage swing of these batteries (10-16V or so) has me concerned. My inverter shuts down if the voltage...

    NiFE batteries from BeUtilityFree

    They are supposed to be rated at 305Ah at a .1C rate, and 250Ah at a 5C rate. You could definitely power a cabin type setup with just these cells. Unlike lead-acids, these cells like to be deeply discharged, so this works out to around 3-4 usable kilowatt hours. I got them because they are...

    NiFE batteries from BeUtilityFree

    I finally received 10 NiFE (Nickel-Iron/Edison) batteries from BeUtilityFree today: http://www.beutilityfree.com/content/index.php?option=com_content&view=article&id=44&Itemid=129 Since these batteries where once used by electric vehicles back in the day, I figured someone here might know...

    50 mile commute - ebike?

    Up to 20mph on the bike paths, and around 30-33mph on open roads. Peak speed is 38mph. There are a lot of starts and stops due to lights, which don't help.

    50 mile commute - ebike?

    To give you some perspective on how challenging this could be: Occassionally I'll commute to work on my c-lyte 5304 ebike. It's a ~15.5 mile trip each way through the Dallas-Fort Worth metroplex: http://www.bikely.com/maps/bike-path/West-Plano-to-Dallas-TX I've optimized the route over time...

    How do you charge your A123 cells...

    The Hyperion chargers are very nice products, but this model is only capable of 10A. Also, hooking up two batteries using two LBA-10's in series, and timing everything just right, can be a bit tricky - not something I would like to do every day after work. With CC-CV power supplies like the...

    How do you charge your A123 cells...

    I finally gave up trying to keep my A123 packs perfectly balanced after each charge. I rarely discharge them more than ~80% so it's not been an issue. For day to day "bulk" charging I use three Mastech 30V/20A CC-CV (HY3020E) power supplies to charge my packs. Each charging cable has a big...

    Full suspension VS no suspension

    With a full suspension bike, the wheels should spend more time gripping the ground and less time bumping all over the place. So maybe the overall efficiency at the same speed could be higher depending on how rough the terrain is. I've put several hundred miles on my two ebikes - one a downhill...

    Mounting 5304 motor

    I too got my rear 5304 from Poweride, it came with the same white plastic cover (bushing?). I wondered if I was supposed to leave it on or not. I tried installing the wheel with the plastic on, but as I tightened the nuts the plastic cover started to break. So I just installed it without the...

    my new ebike

    Yea, thanks for the suggestion. I've been worried about this issue. The rack is rated for 25 lbs, and I was hoping to stay below or near this weight. I'll be making some changes soon, because 48 M1's aren't nearly enough to keep this motor fed at the range I need. To answer the previous poster...

    my new ebike

    I guess I've been reading these forums too much. My wife thinks I'm kinda crazy for spending so much time on this stuff. Not many people ride bikes around here, and I've yet to spot anyone with an ebike in the Dallas area. Anyway, my office is moving soon, and I wanted to build a new bike...
