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

It's a bike for an adult. The ride is comfortable, once you install a superior quality crankshaft and bottom bracket. Any basic/ entry level Shimano or SRAM parts should do fine. Don't break the bank by purchasing overly expensive components. I got some good deals and upgraded with very good SRAM components parts.

It is well balanced and cranks easily. You tyrn it at one revolution per second, so it's a slow turn. I am 75 years old. If i can do it, anyone can.

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

Having had to open up the new unit to fix one of the two main bearings on the pedal assembly (should be enough to convince anyone not to buy it) I can see that the bearings are held in with a plastic bracket so I wouldn't suggest putting too much weight on the pedals. If you break one of those brackets then this thing will end up as garbage.

Hi Tavia, no you can push the ladder in and out without the crank. You can also raise it without the crank, However I don't like pushing it DOWN by force, although its happened before and still works fine, it takes some force to push it and I don't want to take the chance. Overall a very sturdy toy

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 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.

yes its easy to assemble ,they also provide a step by step video on a dvd. its 125cc.my weight is 190lbs and it did not pull me around very well and it had a top speed of 37 mph .i put a larger sprocket on it . it now climbs any hill i can find with a top speed of 25 mph.

Sorry, I didn't post my entire results. I ended up replacing the DC motor for the bike twice. The second time was a charm. I now have two good control panels. I would recommend requesting the DC motor. It is not easy to replace, and there are no instructions included with it. I spent a bit of time fiddling with it to make the resistance appropriate.

just get a new chain and you should be ok if you have a good tech. It shouldnt impact it. I have a 105 group with Ultegra cassette and dura-ace chain.

120. The breaking Power is not so good. And the 1st gear changes too quickly. So you don't have time to enjoy it when climbing a hill. There are instructions one the net on how to fix that. And use a front brake to be safe. Cheers

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.

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.

You can combine this freewheel with any Crankset you want. Determining factor is the length of the chain.

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.

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.
