Imagine commutes with no troublesome hills, no tired legs and no sweating! Trek makes it a reality with their 7200+ bicycle with electric-assist. Trek starts with a light aluminum frame and a comfortable upright riding position, and builds it up with quality components from Shimano, SRAM and Bontrager for precision shifting and braking. But the magic-carpet ride is courtesy of the smooth, powerful and quiet built-in electric motor that runs off a rechargeable battery. It's a pedal-assist system, so if you pedal lightly, the range is 25 miles, and you can extend that range to 45 miles by pedaling more! It's a sophisticated setup that actually recharges itself on downhills, has no memory effect and the removable battery can be recharged from any wall outlet.

I am a senior citizen who has not owned a bicycle for 30+years. I wanted to exercise for my health. This bike is fantastic. The motor smoothly adds power to your pedaling so evenly that it creates what I imagine a "Bionic Leg" would have. You have a "controller" to adjust the amount of "Bionic Assist" you would like to experience. Once that is chosen you just pedal and torque that you apply is multiplied so carefully that it gives you a sense that your legs are MORE POWERFUL than they actually are. I've had mine for over a month now and would no way give it up. One noteworthy feature is that the battery is very slim and small. It sits under the rear carrier rack. It is barely noticeable. This is combined with a motor built into the rear wheel axle. The motor is remarkably small. The total effect of this is that unless somebody knows what they are looking for they may not even realize that you are riding an electric assist bike. Understand that there is no "throttle" per se that you can turn to make the bike move without pedaling. You only get the assist while you are turning the pedals. However, at the higher assist levels, the pedaling is so very easy that you can go up hills without even panting. When you stop pedaling the bike coasts like a normal bike and the assist is immediately turned off. Make no mistake, when you pedal and the electric assist multiplies your torque, you will have actually no jerky motion or even realize that the motor is engaged. The system is that very smooth. The only time you really get a sense that you might have an electric motor involved is when you engage the regenerative brakes. This will slow down your bike as you go down a hill without your having to apply pressure on the brake pads. When you do this you do get an ever so slight jolt letting you know that a generator is now engaged and your bike is held back. The absolutely only negative thing I can say about this bike is that when I have to lift it onto my bike carrier on the back of my SUV I find that it is definitely heavier than my Trek 7500! I am a retired Physics/Chemistry teacher. The technology involved in this bike is totally fascinating and never ceases to amaze me. This bike is a marvel of modern engineering. YOU can be a "Bionic Man" as far as bicycling around town. Great Bike. I strongly recommend that you at least take a test drive.
After riding my bike my wife insisted we get her one as well. We live half way up a mountain. Its a mountain biking mecca here for those who love the backwoods trails. But for commuting and just getting around it was too much hill. Our old bikes were mouldering in the shed from disuse. I wanted some kind of assist to get up the big hills at the end of the day. I did my research and the Bionx unit is by far the best there is, period. It's not some lame scooter but a bike with electric power assist. You have lots of options on how to use the power assist. You can use it just enough to get through the tough ups or power along at 20mph everywhere. Take off from a light and watch car driver's jaws drop as you beat them across the intersection. We joined our son on a bike odyssey down the Washington and Oregon Coast. He's a seasoned rider and we kept up with all the way where ever he went. By using regen on the downhills we were able to stretch the battery life so we still had half a charge left after our 25 - 30 miles ride-alongs. These are not cheap bikes because the Bionx units themselves are expensive. However we don't regret getting these bikes. We are excited to show everyone who notices how cool these bikes are.
just bought 7200 electric bike and it is truly awesome. i live in pennsylvania with plenty of hills and i go up them with hardly a sweat from the power assist. i took it out today on a 10 mile jaunt and was usually at 20-25 mph on lvl 4 assist. haven't ridden a bike in 17 years so this was my first choice to A. get me back in shape B. have fun doing it. sure they aren't cheap but this bike to me is worth every cent. i can go 15 miles on assist 4 and with a combo 3 and 4 i can ride 20 miles. hope this review helps.
