    Micargi Beach Cruiser

    The subject bike, on CL for $60, had an Amp motor (out of business for 10+ years AFAIK). The battery and other extraneous parts were discarded, the corroded aluminum was cleaned with successively finer grit sandpaper and the frame was painted. The bike runs fine @ 36V with the battery nestled in...

    48V, 1000w globalfreeshipping

    I just installed the subject kit on a Specialized rigid MTB. The service and response to questions from the supplier was excellent. The rear wheel with tire, tube and freewheel weighed 18 pounds, the 30 amp controller and other kit items about two pounds and the complete bike with lots of bling...

    36V Amp Challenge

    I rebuilt a dilapidated, yard find cruiser with 36V Amp DD motor, 22 amp controller and on/off/throttle. The bike and motor were refurbished, and the system runs great on a bike stand, but won't accept full power when I'm on it unless I accelerate very slowly. Also, occasionally when the...

    HELP (Sorry it's so hackneyed)!

    I purchased a cruiser with a front hub motor (Amp "silver", 36V, DD, 22 Amp Controller), and need help. The controller has a plethora of wires other than those for the on/off switch & potentiometer; three hall sensors & five others for the motor; and power & ground for the battery. Can I check...

    Luke Workman ON the Wheel-E Podcast

    Today, Mr Workman, with fascinating (to me) information about batteries, discussed them on electrek's podcast.

    YESCOM 1500w Motor Problem

    I purchased a "yes" 1500w system which seems powerful, but I hear a "groaning" sound from the motor occasionally (can't replicate it here) that sounds like a bad bearing. Should I open the motor and replace the bearing(s) (probably they need to be pressed in) or could it be something else...

    BBS02 Cutting Out

    I have a BBS02-equipped hardtail, coupled with a 52V, 14 ah battery that has been used for MTB during the past seven years and has performed perfectly with no maintenance or problems. Recently the PAS (no throttle) has started cutting out on occasion. It will always "restart" after a few seconds...

    Biktrix Juggernaut XD

    Haven't seen this mentioned here (and will probably be excoriated by the DIY crowd), but the subject bike is rated at 200nm with a mid-drive system on the left side of the bike using motorcycle-sized chain and gears. Price $5K now.

    RICETOO 48v 500w Rear Hub

    COVID boredom engulfed me, so I purchased a "waterproof" RICETOO geared system from Amazon ($300 plus tax, free shipping). The kit included torque arm, rear light, front light and brake shut-off parts (for those who use them) as well as the motor, 22 Amp (AIR) controller thumb throttle, PAS unit...

    BBS02 Challenge

    BBS02-equipped hardtail didn't work this AM; the display lit up, but the motor wouldn't activate. It had functioned perfectly for six years and 500+ off road outings. The connections were intact and the magnet was appropriately distanced from the PAS sensor. Looked like I'd be riding a 50 or so...

    Shimano "Freewheel"

    Years ago Shimano developed a short-lived drivetrain with the "freewheeling" function in the crank, not rear cluster. As such, the rear mechanism only permits reverse movement as a safety feature if the front becomes jammed. Since Bafang BBS mid-drives have a freewheel mechanism in the crank...

    Charging Battery Through Output

    I have a 36V battery that apparently has a problem with the "input" connector, that is there's no indication it's being charged. However, it can be charged through the "output" connector. Is this a problem?

    Charging Through the "Output" Connector

    Accidentally (of course) I connected my 52V charger to the "output" connector of my 52V battery for three or four hours. It fully charged the battery with no excess heat or any problems. Did I do any damage to the battery or charger?

    Luna 52V, 10 ah Battery

    My Luna battery is nearing its fourth birthday (can't remember the exact date when purchased, but right when they started offering them) powering a BBS02 off road or a 1000w DD rear hub for errands. It's operated off road about twice a week and once or twice a month with the hub, so a total of...

    BionX

    A local e-bike store (third oldest in the US, AFAIK) still sells ELBY bikes with the BionX 500D motor and OHM still offers it on some of their models. How are they accomplishing this with BionX out of business?

    Used Bikes

    This might be of general interest. Occasionally I see a bike for sale that appears to have been used minimally, but battery is dead, so difficult to test. What is a reasonable expectation? Is it likely there will be something like a controller that doesn't work and can't be replaced because the...

    Three Years Later, AM1

    Single-speed, 200w, 30 pound, 20 miles range ebike on Kickstarter has collected almost $400,000. Seems like the inexpensive bikes thrive on crowd funding sites since this is a poor cousin to a far superior model that wasn't funded (AIR) a few years ago.

    Shengyi Motors

    I have two identical appearing Shengyi 36V, 350w front hub motors built with identical spokes and 26" rims. Operating them with a 15 amp controller and 36V, 17.5 a-h battery, highest PAS level, one goes 23.1 mph and one 20.1 mph on the stand (no load), so apparently different winds. I a$$ume...

    Frame for Bafang Ultra

    Luna is selling the motor or a complete bike. Has anyone located a frame (only) that will accommodate the motor?

    Maxon Bikedrive

    Probably of limited interest here (maybe everywhere), but noticed that one of my LeBS' has started selling Maxon's, a Swedish-manufactured 500w rear hub system governed to 20 mph here (I think). However 0-20 mph in three seconds isn't terrible (to me). Price a whopping $2850 for...

    TO THE MODS

    Just chastised for defending a vendor and about over ES anyway so here's a few thoughts: 1) Negative reports should be confined to the reviews section and should be about products the individual actually purchased and used. 2) There are a lot of posters with cottage industries who have motives...
