This is like a drug: with the push of a button, no more hill. Expensive yes, but its Sooo nice. I installed this on my tandem I use to take my daughter to school (6 mi each way). I bought it used, with the heavy lead-acid battery, and everything worked perfectly, there was plenty of power for my daughter (85 lb) & I (135 lb) to get up hills easily (with pedalling also). I found I could usually or almost do 2 round trips on one charge, but its such a rude surprise when the battery runs out at the very last hill, I ended up charging it every round trip. The heavy battery is kind of a pain to deal with (moving it off the bike to the charger every night), the weight meant the rack had to be really solid - but acceptable. I found no degradation in the battery life over the 2 years I used it (1-2x/wk)

Bought two kits for me and my boyfriends new 2014 trek verve 1's. Fit was tight in the forks but worked. Had to file the drop outs a little, no big deal. The wheels were a little out of true, my boyfriend true the wheels himself. Lots of fun goes 17.5-18 mph top speed. We can climb hills in our neighborhood at 13-15 mph, while pedaling of course. We got the sprinter 10 mile lithium kit, range seems good so far. We don't mind pedaling, rode 8 miles and still had plenty of battery power. Great product, highly recommended. Thank you
My wife loves it, but it did take some time to set up

My wife is quite thrilled with her new electric bike. She particularly likes being able to get through intersections more quickly -- we have one with such a short light that a bike can get caught in the when traffic starts moving. She's able to go to meetings now without getting sweaty, and to the farmer's market without getting tired from the load on the return trip. The 10 mile battery seems more than enough for her use. She uses it in short bursts, and it lasts quite a while. I am also pleased overall with the product, with one caveat: the wheel was significantly out of true. I was able to bring it back, but I think it could have been shipped much closer than it was. I also had to file down the slots, and spread the fork (used our car's scissor jack), file down the shoulder of the hub itself and add spacers to get the wheel to turn freely. Took about an hour total. The forks are pretty fat on her 29 year old Bianchi, so it's unlikely that most people would have to do this.
Lovin it!

I have been using my Hill Topper for a couple months now. It was totally easy to install on my Trek bicycle. I already have 160 miles on it. It makes it easy to maintain speeds of 18 mi/hour on level ground and makes going up hills much easier. I now use it for my 3.5 mile commute to work. It is fun!
Got another one!

My wife was a little jealous of my hill topper equipped bike, so I got her one for her birthday last year. It did not fit on her mountain bike due to a fat fork, so we shopped around and were lucky to find a great used mountain bike. The owner had converted it to a commuter w/ thinner tires and fenders. We added a rear rack, more upright handlebars, basket and pannier and lights. The hill topper wheel hub just touched the fork on the right side, so I talked to their excellent help on the phone. I moved a washer from left to the right side as instructed and it fits great. We had a wire come loose and it was replaced w/o question. My wife prefers to use the motor only on the long hill climb to our house, but is glad she has it on the flats if it is a long ride, especially if we are loaded w/ groceries. She also likes to get a boost when starting through busy intersections in town. She weighs 100 lbs, and I didn't know how much difference that would make, so I made sure her bike had nice low gears for the steep climb to our home. Her light weight makes a huge difference. She goes up the hill much faster than me (175 lbs) and in a higher gear. She loves her hill climber as much as I love mine. I have had my (20 mile li-ion battery) for 3 years now and it has had no issues.
