Amazing and I love the idea, but they are insane asking that much. I understand they have to pay for the R&D that went into, but I think they'd be better off selling it for half and selling a lot more units. I would seriously look into for around 1000$, but certainly not twice that. They mention kickstarter, but when you click in the link it just takes you to kickstarters main page.
I bought 1 over a year ago (or rather I payed for it over a year ago) and it finally arrived this past winter. You need a bunch of parts from both a pit bike & a DH mountain bike! I have tons of mountain bike parts, but decided to go buy a brand new pit bike from a wholesaler in Concord!
The project was started, but was then put on pause when other things got in the way. I am now hoping to get back into it & build it up completely.
Yes it's not street legal here in Ontario (unless you register it as a 50cc moped), but I intend to ride it off road anyways. Instead of buying various parts for the build from numerous suppliers/ resellers, I decided to just purchase a new pitbike that would supply me with the engine/ carb/ electrics/ tank/ throttle/ seat/ fairings. I did the math & this was the most cost-effective route for me at the time. As for the DH mountain bike parts, I am using a Marzocchi 888 dual-crown fork, with hydro 8" disc brakes, 26" mtb front wheel, single-speed crank arms (square taper) & DH type stem & wide handle bars. The kit comes with a special 36 hole rear hub that needs to be laced by your local bike shop when you purchase a 36 holes 24" rear rim.
All in all, based on my experience with just the early stage of building this kit. Yes it is pricey & consists of many bolt-on parts that need to be purchased seperately. But there is nothing else out there that permits you to pedal like a mountain bike or ride it like a dirt bike!
This kit also has future potential of becoming an electric powered performance bike (E-bike). Some have already started converting these into high-powered ebikes on endless-sphere!
The reason why they are such expensive kits, is due to a small production run order from China! If more demand grows for these kits, then orders will increase & prices will come down (but just for the frame kits)!
Most buyers build these up themselves, but I believe Pirate Cycles in the US is selling a complete built up Motoped with various engine/ colours/ other options.
*** I'll try to post some pics in the next few weeks as my build comes together.
Cheers.........
