Yo, Canadian New Guy.

Welcome to the forum from another newbie. Did you check to see if your rear sprocket was not true? Also check if the chain is getting caught on something.

Good intro post. You've told us a bit about your bike and what's happened with it.

Sorry about your bad luck. Chain de-railments are not uncommon with newbies. Make that motor stay exactly where you put it. Most of us learn this by trial and error. But you can pick up some very good hints reading these threads. You also want to make sure that the drive sprocket is installed well. Straight and true. Beware the chain tensioner; it can also destroy spokes.

Elbow (and knee) pads are a very good idea. When doing any real riding, I wear 'em. Plus gloves, decent boots and a helmet. Maybe I look like a dork, but that's very, very low on my priority list.

I'm afraid that I didn't understand the bevel drive gear that you mentioned. But the answer to your other question is 'yes'. Unfortunately parts do break on these china girl kits. They are just not super high quality. But, like an old Volkswagen or a Chrysler from the 60s or 70s, they're still (strangely) lovable.

My answer to the parts issue; a second motor and kit sitting in my attic. Basement might not be a good idea; too moist. When I need a part I take it out and then order that part from one of the vendors that you'll find in the margins of these pages.

Have fun.

Good to hear you weren't hurt more seriously and that you are getting solutions to the problems.

The pictures are not showing up for me, I use Maxthon 3.4.5.2000 browser.

I look forward to seeing pics when they are working.

Welcome to the forum. I think you need to post three times before you can post pics, but if you make an album you can link to the pics right away. Check with the vendors on the sidebar ads for the part you need. Some are better than others, or so I've heard. A little reading in some of the forums will give you the idea.

Canada... what part of Minnesota is that in? LOL
Seriously, welcome, welcome. You are in the right place, lot's of good help here. I have the 49cc Grubee stage III, and have had no problems. That's the deal with these kits- never perfect, usually good, sometimes bad.
You seem to have things in hand, removing the chain tensioner and what not. I recently laced my first wheel, and after really seeing how lightweight the materials are, I am pretty worried about failures. Glad you lived through tearing yours up! Make sure everythings' tight and true, and ride it.
I believe it would benefit you to replace the cheap Chinese bolts that came with your kit. I recently installed American made fasteners in mine, and it's great. They fit better, and I wasn't constantly worried about snapping them off.
Most important is that you got up and got back on that contraption. You're already hooked!

(still can't see your pics)
