Thankyou Roland, this is 8051, just built-in model.
Chopper is a little more simple than the default mod.
Well, next model will be 8051 monster-style mode.
Thanks for commenting!, Big hug AFOL community.
The rear wheal should be wider, doesn't it? But all in all, great model, nice technical features you've put in there. And I think it is harder to build accurate bike than car, so you've done an awsome job!!
