Bent crank arm! Need replacement ASAP. What are my options?

[The Flying Dutchman]

Got a little carried away yesterday and now have a bent crank arm #NoRegrets

It's not clear to me what replacement arms are compatible with my Giant Trance so I'm asking all you internet experts.

Was looking at these: Aeffect e-Bike Crank Arm

Will they fit????

I bent mine as well and ended up getting the Praxis Alloy which is exact replacement for OEM Alloy cranks on the Giant Trance. Price was right at $65. ALLOY ISIS eCrank - Praxis Works

Raceface should work as long as you get the crank for ISIS spindle.

You might consider going shorter. I did and love it.

What did you go for? 170mm? 165mm?

My bike came with 175, after 2 months i moved for 165. Here it makes a big improvement.

excuse the personal question but how tall are you? Did you notice a drop in power output?

It should be noted that red is presently looking for even shorter cranks to try.

There are quite a few threads on here about people putting shorter cranks on their emtb's. There's also lots of theoretical views on why it would be worse .. I put 150's on my Shimano and its' great. Seems faster uphill and downhill ..

I am 61 YO. now 5 11 with 34.5 inseems. I noticed 1 thing, less strikes wich is safer. The side effect is more flow. We adapt maybe i use different gears but who cares. I still have a good position sitting or not. Usualy shorter is better to climb, less dead spot, but i was OK so no improvement. Less power is a myth. The transmission does the job, it happens naturally. I understand 175 for road, not mountain. If mountain was first 175 would not be an option, it was imported.

Anywhere have stock of the Hope 155mm ebike (Isis) cranks?
