How strong is the chainwheel? Will it bend easily if its hit against stairs? Is it removable... can I upgrade it without having to buy new cranks?

It is strong but it has a flawed design but i have put it through some beating and it never has bent on me, the bike is totally worth it , you should think about switching the crank out tho after some time

Hey Tim, The upgrade is about $60. I'd suggest trying the trike as is for now, that's a very easy thing to upgrade if you feel you need it in the future.

That's not a chain you're seeing. It's a long rod that bends into an "s" shape and you crank it. Very easy to crank.

I fully agree with this statement. I purchased this bike for the frame, fork, seat post, stem. I have had to upgrade the crankset, handlebars, seats, tires, tubes, peddles. They are not of quality. I now have to upgrade the bottom bracket as the bearings just shattered.

The crank appears to be unique to the Schwinn AC bikes. I doubt you could swap for something else.

I should probably preface my comment by saying I'm not super knowledgeable about bikes, but yeah I think you should be good as long as you're not planning on going off road. The portability of this thing is great. I stash it in my car and bring it up to my campus from the parking garage below every day. It unfolds quickly and collapses easily. Just keep in mind that the front reflected can snap off like a twig so be prepared to replace with another one.

Nothing. The first bike I purchased had fully assembled, except for one pedal that would not screw in at all. It was a major pain to dissemble the bike completely and "try" to get it back into the carton so UPS could pick it up. The second bike assembled with no issues. About 9 months later I started having the same issue with the pedals coming off. I finally had enough and ended up giving the bike to a local charity since I rarely used it anymore. I suppose you could try super gluing the threads on the pedals or on the crank arm when re-attaching. Of course if you ever want to change out the pedals it may not be possible. Now that I think about it, I even had the same problems when I used a set of clipless pedals with the bike. So this leads me to believe there is an issue with the the treads on the crank arm.

If you clamp to the seat post or top bar the cranks spin fine. Depending how its mounted you may not be able to move the handle bars but there should be enough space unless the bars extra wide. I have this and have used the park tool wall mount and there isn't much difference.

Replacing the crank set is really not that difficult. The hardest thing I think is deciding how much you want to spend. Crankset can cost up to $500 and more. If you are not changing the derailleurs, you probably need to get a crankset with the same number of chainring as the old one. check out this video "How To... Replace Your Crankset" on youtube . I'm sure there are other videos that can help. Good luck...

if you know a little about bikes you can just switch the back wheel, you must know how to tighten the chain though, witch is the real challange, i would just take it to a bike shop, they shoulnt charge you more than 15 dollars

Yes and no. You can if the bike is firmly secure and doesn't "pivot." But if the bike "pivots" or leans to the inside then the pedal will hit. All in all, I would answer that Yes you can pedal it fine. I will be honest. I bought this rack for general repairs and I absolutely love it. I would highly recommend it for general maintenance and cleaning. The only addition I made was buying the Park handlebar stabilizer. That comes in super handy to hold the handlebars in place.

like the bike a lot, should be OK for you, but I agree will not get you up a hill...you need more power...

holy smokes! what are you carrying a car battery? If the bike is balanced well, it should hold the weight but i don't know how stable it would be. I have put bikes that i think weigh 35 pounds on it. The cradle for the bottom bracket is basically hard plastic. if you're just doing routine maintenance on the bike it should be ok but probably not serious wrenching. i like my park tools 10 or 9 (can't remember). i had a tandem on the Park and it was a little iffy. Probably close to 70lbs but longer than a normal bike. Personally i think i wasted my money on the RAD.

Very.... Essentially the push of a button... The quick release skewer is junk, and I'll be bitchin' about it and demanding a replacement, but the mounting and solid axle setup is solid.... Feel free to contact me with anymore questions you might have... I'm a bike mechanic with 30 years experience, and a borderline activist, so will answer questions with everyday biking in mind.... Be safe, have fun, and support cycling!!!

The left is friction so it will do 2 or 3 chainrings on crank - versatile.Right is 7 spds, but I've used it w/ an 8 spd, you just miss a cog at top or bottom.Fyi: 6,7 & 8 speed use same basic chain & gear spacing, so interchangeability is nice.

I believe it is a standard Shimano single chainwheel crank for a 20" bike with folding pedals added. Your local bike store should have no problem getting one. Every thing is pretty much generic Japanese standard (yes, I know it is a Chinese bike pretending to be Italian).

The crank is used to raise and lower the ladder and sometimes gets stuck. We have pushed it down several times until it catches in the right place and it still works with the crank. However, if you did it all the time and roughly, I think it would break eventually.
