I have an Trampa style off road/AT kit for sell, which I purchased a couple month ago form Maytech. I tested it for 2-3km and decided that it’s too soft/carvy for me (100kg equipped).
The kit includes:
2 channel spring trucks
2 motor mounts with 30mm bolt pattern
2 angled rubber riser
mounting bolts
4 200mm off road wheels with metal hubs
2 72T metal pulleys
Price is 249€ + shipping
I paid 370€ incl. shipping, customs, tax and 5 weeks of waiting.
No, just if you add an adapter for idlers or tensioners. But the 380 sits quite snug though. I can add the if needed. Increasing or decreasing the motor pulleys by 1T or 2T does also help, but like I said with stock pulleys/belts there is no need for it.
FYI, this is the 2015 version of this kit and there have been 4 iterations. The videos you posted aren’t of the same drivetrain
Its still a pretty good quality though, GLWS
