Powell Challenger?

In my search for a mini bike frame to copy when building my trail bike, I came across the Powell Challenger. I really do not know that much about mini bikes but really liked the look and utility of this bike frame.

The foot placement is also pretty cool and simple with the tray design.

How did this mini bike handle?

How well does the frame hold up over time?

Is there any weak points in the frame that should be addressed.

I will be doing a frame from scratch so I will be able to fix or improve upon the design.


Does anyone have a picture of how the swing arm is setup in the back without the tire?


Justin

JustinJ ; Well I am a bit opinionated about Powell's as I once was a dealer for that line of bikes. And the frame design is very strong but not overweight. One factor is the working suspension that takes the shock and stress of heavy off road riding. And the large wheel size gives the bike a good ground clearance.
If you look into my picture section there are numerous articles about the Powell and it's evaluation . As for improving a tried and true machine just think about that. I has a mono sprung swing arm and absolute dead on chain alignment a thing that most mini bikes with jack shafts do not have. Being that the pivot of the swing arm is also the drive sprocket mount. That is on the Phantom 7 series.
Here to help in any way. Steve

im not opioniated, im sold on the powell challenger style, if you want trail riding and wont be ridiing at pismo beach always,this bike has really great features. been really nice riding on the road and offroad in my experince with them. ive had all kinds of hardtail bikes and
the suspencion sure is nice. has tall wheels and looks so nice and well fitted with the five horse motor tucked into the frame. great seat and bars.
i dont know anything about the phanthom bike but im sure they are just as great.

Could someone take a picture of the bottom of the Powellr frame? I was able to find a picture of the frame sitting on the ground but would like to see a picture of the frame looking down on the bottom with the top of the frame sitting on the ground.

Hi Justin, I and my brothers have a few Powells, however not as many as James. They are everything others have described. There is numerous build threads on OMB; a good place to see many closeups pics. We have noticed that the goose neck seems to be somewhat of a weak point. There are many Powells around with the fork angle off, goose neck bent, and/or the top bar slightly bent from probable front end wrecks. This is really about it. If you were making one from scratch you may want to consider a full torque converter, Powells only had a variable Driver, not Driven. I am currently in the process of changing an original Powell I have to a full TC, along with a little more power. The project is on Omb. Belong that, the Powell is an amazing small trail bike.

David just pointed out to me that this is a very old thread, it would be cool to see someone build one however.
