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

As cheap and sturdy as these little bikes are, just upgrade\ crossgrade to new parts that fit your aesthetic choices. Look at citygrounds.com or even

I traded this bike in for a better model. After my 4 star review, the pedal cracked and I had to replace it ( 1 weight 180 lbs). I sold the bike to a friend and bought the higher end model used at the gym. I am very happy I did. These bikes weight 100 lbs (give or take) but I suggest getting the higher end model. I had no problem with shipping because it was included in the price. Assembly was not a problem. Updgrade to the higher in bike like I did.

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 put it in my old steel bike. I wasn't afraid to pry it apart a bit. In fact, I sneer at those who say folks like us can't just do that. I don't believe the frame weldments are particularly precise to begin with, so it's not a big deal in my mind. You just have to be sure to position the wheel so that the brakes and lower fork don't rub and you're good to go IMO.

I would suggest to get a name brand one. I just use this for bmx and dirt jump style bikes and it is pretty wimpy and doesn't hold very well. the parts aren't very strong. hope this helps you out with your purchase.

I completely agree with Sandalsallyearlong, I had the 5914 and with all of the flimsy plastic parts, it broke after the second use. I got the 7411 after a lot more research, and have had no problems with it. However, I don't take it up and down the stairs. I think for the extra $50 you can't go wrong with the more sturdy 7411.

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.

The higher the resistance, the more likely it is to move but movement should be minimized if you use it correctly by pedaling up and down instead of forward. Mine is located under my office desk in a location where it rests against the back side of the desk, so it has no forward movement. I had no issues at all with lifting, twisting, or lateral movement. It is heavy. Some of my coworkers settled for the $30 models. They move around a lot, get really hot, and the resistance cranks do not hold the resistance. You get what you pay for.

Anyone could steal the motor with a few tools. However, I think it is unlikely.motor is slow and bike is inexpensive. Your going to want a faster bike pretty quick. Also, motor is loud compared to HUB motor

I've been using this bike for the past few months and have been please with it's performance. It's a lightweight aluminum bike. I live in a 5th floor walk-up apartment building and always need to carry this bike upstairs, and I haven't had any major issues so far. It's still heavier than the more expensive road bikes, but only marginally so. Hope that helps!

It comes with a crank handle. You can remove the handle and replace it with the motor, which is sold separately.

I don't believe there'd be any problem structurally but moving it might be a bit clumsy. The crank handle's moment arms are only ¾" or so off center so that heavy a load will require a lot of torque.

Yes you have to play around a little as i did. I switch out the sprockets on mine. That`s just that my chain is two links short, but it should work well. Remember i used my old sprockets, just clean and grease them.

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.

I actually just did a 1x10 conversion with 32 tooth up front and a 42 tooth in back. Still works flawlessly. Definitely start with a new chain though,narrow wide chain ring up front and One Up extended cog in back with the special mad 16 tooth cog that replaces your 15 and 17 tooth cog.
