SOLVED Woo hoo!!!!! Issue solved-it was the front chainring!!!! Changed out the 52T to the original 42T, removed a total of 4 chainlinks and added a masterlink, to prevent chain stay slapping yet still shift smooth in all gears. Kept the same 152 mm cranks and it works great!!!!!! Instant...

Ha! I'm less than 86 and pretty active (walk/bike/hike/yoga) with no knee/hip issues so far and hope to be as active as you are in my 80's too :)

Hello PedalUma! I will try starting the display while pushing the pedal backwards or rolling bike backwards and report back. Might swapping the 52T to original help too? I thought I wanted a 28mph capable ebike but now second guessing the safety of riding at 28mph on 20" wheels on crappy LA...

I just came back from a 40 minute bike ride after recharging battery to 80%, about 8 mile total urban riding (potholes, uneven pavement, construction, stop signs, traffic lights, cars everywhere!) so lots of stops/starts, grade going slightly downhill and then uphill on the way back. I feel the...

So confusing- I thought mid drives, especially with the TSDZ2B's smaller motor, likes high cadence low gearing to avoid overloading and stripping out the blue now white gear? My bike has 9 gears and I down shift to 2 for stops and spin as fast as I can while shifting up to gain speed and to try...

Thank you! I'm hoping PedalUma will chime in as well- he is the TSDZ2B expert! I had the original 170mm cranks initially and the same clunky pedaling. I switched to 155mm straight cranks b/c the stock angled cranks wide q factor and offset right crank was too wide and uncomfortable. Plus my...

Are you riding stock or with osf? How's the assist feel on PAS 1 and 2? I can hear motor turn on when pedaling immediately but with that odd clunky pedaling on PAS 1 and 2.

Yes, I bring my bike out, flip the kick stand and turn it on. While its booting up I'm locking my door, putting away the stair ramps...not timing it but I'd guess its at least 10 seconds?

SOLVED!!!! The clunky pedaling was due to the 52T front chain ring. I put the original 42T back on, shortened the chain (stock bike was 52T) to fit and it works beautifully with no clunky pedaling no matter the cadence! Thank you all for your suggestions!!!! I added a Tongsheng mid drive to a...

I bike (regular pedal bike) to work and have done so for nearly a decade in LA (California). The main reason why LA doesn't have more people using bikes for transportation is lack of bike infrastructure. We have plenty of space for it but no political will to make it happen. I still use my...

They replied but none have short crank arms w/0 or low offset. I found and placed an order for these- Samox 155mm cranks 5mm offset They have 5mm offset but still lower than the 18mm or more Bafang 152mm cranks and made of alloy vs steel. Cancelled the steel unicycle cranks. Looking for a...

Thank you. Do the cranks you got for your wife have an iffset? I looked all over and aliexpress but they all seem to have offset and I’m looking for 0mm offset. AliEx has a few 0mm no offset cranks but they have a chainring attached and are 170mm. I did message a few to clarify if any have...

Ended up ordering this: Its a 152mm straight crank for a unicycle so the overall width will be narrower- I'll still have the offset on the R due to the motor but hoping the reduced width will make my right foot happier. I rode my regular bike (has 150mm cranks) into work today and its easier to...

I might try a 170mm Bafang straight crank for the R side. Will I need to mill it for the R side too? http://www.schlumpfdrive.com/index.php/cranks-safety-strips-easy-shift.html There are Schlumph 155mm straight cranks- that will give me shorter cranks, narrow the overall width but still retain...

Yes, I looked up Lekkie cranks, they have 160mm cranks w/the R straight and the L offset. I don't think it will narrow the distance but make it feel more balanced? Or try a 170mm R Bafang straight crank...

Yes, saw Electrify Bike specifies their cranks are 0 offset (but OOS for a while now). Saw others online- they don't specify 0 offset or are the same standard curved (15mm offset?) but just shorter. I checked aliexpress/amazon/ebay searching under - 152mm, straight, 0 offset aluminum cranks...

I would like to get cranks that are 152mm that minimize the imbalance- to help me make smaller circles (28.5" inseam/short person). So maybe I need to buy two different 152 mm cranks- L w/offset and R straight?

My other bike measures L 65mm and R 62mm. So same distance on the left but 32mm difference in the R.

I'm still trying to get used to it but my right foot wants the pedal closer to the frame. I flipped my bike and took measurements between crank and down tube. L is 65mm and R is 94mm. Are there replacement cranks that bring the right crank closer? And considering shorter cranks. I have 150...

First ebike conversion COMPLETED!!!!! Many thanks to all here, especially to PedalUma for his guidance and patience! Peppered him with lots of questions! It all fits! Works! And looks great! Also discovered I’m more of a masher than a spinner :( I’m learning to be a spinner- any tips...
