    Donor bike for rear hub motor

    Having done something similar to this on several Ebikeling conversions, I do not think you’ll have any major problem. Your 8 gear shifter ought to work reasonably well with your 7 gear cassette if you adjust your derailer range to not go beyond a certain range. You’ll just top out at 7 gears...

    Ebikeling 1200w rear wheel kit from Amazon

    What are these (rubber?) rings? For the wheels around the inside of the wheel base? If so, purely cosmetic or for hub protection? This is the material (cut to size) mounted to the water bottle frame holes (2 screws and 2 zip ties) and bag. The bag is mounted to the (board inside mounted to...

    Ebikeling 1200w rear wheel kit from Amazon

    I do have this alarm thing mounted to the rear rack (between rack back and seat). Move the bike a millimeter (when armed) while trying to cut a chain lock or cut a luggage lock (on the bags) to try to steal a battery, it screams at 113 decibels (after a warning chirp). Ear-splitting! Onvian...

    Ebikeling 1200w rear wheel kit from Amazon

    Alright, Harry, I officially lost my mind... - I added a third 20 AMP hour battery to the frame (three 20 AMP Hour batteries in parallel now) and now might be able to make it to Madison, Wisconsin from Chicago, Illinois (~144 miles ~ 2,880 Watt Hours assuming 20 WH per mile). The battery was...

    Must be a Toronto thing. In Chicago, annoying and excessive alarms command respect! ;-)

    Winter e-biking advices

    Ebikeling 1200w rear wheel kit from Amazon

    Yeah, I’ve been using them a few days now on my Chicago commute on my super heavy fat bike where I need to stop and slow down a lot. Night and day from mechanical disk brakes! I My hands used to get tired from all the super hard squeezing mechanical braking required to slow down fast. I also...

    Ebikeling 1200w rear wheel kit from Amazon

    I think 750W is (technically) the Illinois limit along with 28 MPH but there are very few ebikes in Chicago and seemingly no rules (enforced) for cyclists as a whole. I read the regs recently (standard 3 classes), but it was very unclear what was actually kosher and what was not. I pass cops...

    Ebikeling 1200w rear wheel kit from Amazon

    Hi Harry, I ended up swapping some batteries (between 2 bikes) and running them parallel after all (2 identical 20 ah batteries). The controllers might draw up to 26-27 amps each, and each battery has 50 AMP continuous discharge, so parallel seems to work well. I also am only using the front...

    Ebikeling 1200w rear wheel kit from Amazon

    Yeah, the batteries all fit in there (along with 2 controllers). I had to play a game of Tetris to get things to fit efficiently. When I increased from 20 to 40 AH, I lost most my storage space although the rear rack bag has relatively sturdy side (unzipping) panniers. I’ve also got the...

    Ebikeling 1200w rear wheel kit from Amazon

    Harry, Here’s what she looks like done. I hooked the single throttle and single PAS to both controllers with separate displays. I think I’ll likely end up keeping the front set to a slightly lower throttle and PAS setting than the back. I haven’t opened her up yet, but I took her around the...

    Ebikeling 1200w rear wheel kit from Amazon

    Harry, Just curious, but what was your reason for scrapping? Bronchitis caused by riding in the snow (making a high cost build a waste of $ and parts), or was it that the 2 motor build was not effective for the added traction (in slippery conditions) you were seeking, or that acceleration or...

    Ebikeling 1200w rear wheel kit from Amazon

    Thanks, Harry. I realized during the first Chicago snowfall, they plow the snow from the streets into the bike lanes... Glad I have a couple of snow bikes! It appears the brake levers can be merged. I may tinker with getting the PAS (and maybe) throttles connected to both controllers.

    Ecotric 20" Folding Fatbike

    Hi Harry and/or other tinkerers, I’m seeking feedback or comments about an all wheel drive (front and back motor wheel hubs) EBike configuration on the (Saigula) fat bike pictured below (now with proper fenders and winter-proofing). I have the 1200W (Ebikeling) kit rear wheel install already...

    All, I’m seeking feedback or comments about an all wheel drive (front and back motor wheel hub) EBike configuration. I have the 1200W (Ebikeling) kit rear wheel install already on my 26 inch fat bike set up with left grip twist throttle and PAS. I get decent but not great acceleration/torque...

    By the way, this is the fender set I use on the X-Treme E-Rider mini. Nothing fancy, but they fit well and are < $20. SKS Rowdy 20-24" Set BLK https://www.amazon.com/dp/B0013CVZGC/ref=cm_sw_r_cp_api_i_3A0YDbQZ1YA7H I also used this $21 rear rack, which fit: Ventura Universal Bike Rack...

    X-Treme E-Rider 48 Volt Mini Folding Electric Bicycle vs. E-Joe EPIK SE

    I really like it as a smaller folder. Durability has been been good, and it’s compact but still fits me well at 6’3 and 220 lbs. I haven’t done a real full range test from full charge to dead, but extrapolation of a couple 10 mile rides gives me reasonable confidence of a 15 mile minimum...

    Trek Verve 4 - suitable for conversion?

    I used a Trek Verve Disk 1 recently (same frame as Verve 4) on a 1200 W Ebikeling (rear wheel) kit, and the frame is plenty sturdy. The disk 1 doesn’t come with a suspension fork, so I added an air fork though. I would echo others’s comments on going with disk brakes. The ~$450 Trek Verve...
