Intelligent power assist system (I-PAS) is patented technology of Rattan Team. Featured with energy conservation and generation.
I-PAS motor after being optimized, can easily make the efficiency more than 83%, under intelligent controlling , can be realized the seamless switching between drive and generate.
The System has achieved two major breakthroughs: One is comparing to the traditional control system it saves more than 50% of electric power.
The other is that the kinetic energy could be collected while the bike gliding and downing hill, and convert it into electrical energy by I·PAS system, which can be stored in batteries.
For example, a mile of downhill kinetic energy can be converted by I-PAS system, allowing the bike to ride an extra mile on flat road, furthermore keeping the battery more active and prolonging its life.
You get not only a cool bike, but also the beautiful scenery along the way.

we received our bike a few days ago and I have to say we are very impressed with it. When I ordered it I was very Leary about what the quality would be like but I have to say it far exceeds my expectations. The bike took me about 20 minutes to assemble and works great.
I really love this bike for the fact that with some health problems I am able to ride a bike again.
If something were to ever happen to it I would buy another one.I haven't had it that long yet but so far so good.

I ride my bike to work which is about 5 miles to work. I can ride this bike to work without getting sweaty with the pedal assist. I have been able to use pure electric and get up to 20 miles/hr. I have put ove 1,000 miles on this bike in the last 7 months.
