Stronger Crankset for Ezip Trailz
I want to replace my crank arms with something stronger so that when the bike falls I dont have to worry about bending the arms back into place. Is this possible?
Has anyone done it before?
If so, what did you use?

If you can bend the cranks at all, they are worthless and you need to replace your bottom bracket too.
I use RACEFACE brand
Those can outlast 5 Ezips bought one after another /when they last like 2-3 years each/.
they cost $$$ of course
but seriously installing those work of arts on this...... would be profanity.

Why is the bike falling in the first place? Maybe you need to change where/how you park it or consider looking at a different kickstand.
each time it has fallen has been my fault. First time I was speeding in the rain and decided to make a hard right down a hill.
second time is because the newly poured sidewalk they put up on my street wasnt quite ready for prime time. Hit an uneven section and the weight of the batteries took me to the ground. My thigh was sore for 3 days. Oddly enough I enjoyed the pain though as it is the most I have had in years.
Never has the bike fell when parked. I have a double legged kickstand and dont have to worry about that.
Also, My bike is a work of art I can get up to 30mph on motor alone. My last experience with replacing keys has taught me a great deal about when to apply that extra torque though.
The good thing is you aren't getting badly hurt when you take your tumbles. But for the most part I would hope that these tumbles are rare and won't keep happening. I guess I'm saying why fix something that isn't a common problem. Would you buy custom heavy duty bumpers for your car because you keep driving into things brick walls? Keep in mind the whole point of the EZip is "low cost". But if you keep spending money on repairs and modifications you could have invested bigger money upfront and gotten a higher end bike. LOL, look who's talking......I could have bought a good motor cycle for what I have invested just in my lifepo packs. Hmm, that's right I did buy that motor cycle! All joking aside I have dumped my old Zip (don't actually ride the Zip anymore) and rolled it down the hill with me but never bent or broken the crank arms. But it did bend the crank sprocket which i straightened in the vice. Personally, I'd just fine a cheap set of cranks on EBay for 10 bucks and keep them as a spare just in case. But that's just me cause I don't see having a crake set that costs more then I paid for the bike. Stay safe and upright.........
Luckily I havent broken bones or anything like that. I chalk the dumps up to learning the bike. Most of the things I have purchased so far have been the utility bag or lights. You know the usual stuff.
I'm concerned about the cranks though because twice I have bent them back into place using an old basketball hoop pole. Worked perfectly. The question is how many times will I be able to do that before they break though?
The do ALOT of roadwork around here. Especially right here by my house and I want to try to keep everything in tip top shape as I have already been offered everything from cash to scooter trades for it.
My next purchase for the bike is supposed to be a new battery setup but, since stuff keeps happening I'm spending money on tools and parts. However, I am learning and am not spending any more money on repair labor at the bike shop. That's a definite plus and the tools and parts are good to have around anyway.
Also, I do all of my shopping on ebay and amazon so far. I try not to pay retail for anything if I dont have to.
So any crank set I do decide to jump on will be an awesome deal. Just need to know what fits and some popular brand names.....
Your cranks are already shot and need to be replaced. That they have not cleaved in two is just luck. While you have them off the bike you need to replace your bottom bracket as well. I seriously doubt that the bottom bracket has faired well when the cranks first bent or were torqued back into place.
Look at Shimano or another like maker's mountain bike cranks. I have Race-Face cranks on my bike and they have served me well.
You don't need the top end model cranks, just pick a set that is within your price range. Same goes with the bottom bracket. You may have to have them installed by a LBS. IIRC a bottom bracket requires a special tool to remove/replace it.
