I've been paying close attention to the e-bike business since buying my Optibike, and the more I learn the happier I am with my choice. There is nothing out there that is really comparable. The motorized bottom bracket is the cleanest chain drive system I can imagine (and I have a pretty good imagination). The internal battery and electronics are mounted out of sight and protected from the elements inside the frame. The heavy parts are isolated from the road or trail by high quality full suspension components. Efficiency to the road was measured at 87% by an owner, and, unlike hub motors which operate without changeable gears, that efficiency is available over a wide range of speeds.

The 800Li is a hybrid bike for people who want to ride pretty fast and well as those who like to ride hard. 25 mph now feels slow to me, and I often ride at 30mph or more. The controller boosts the power to 2400 watts during acceleration, so you might well be surprised at just how lively it is when the light turns green. At least one Optibike owner is an ex downhill racer. Another commutes year round over hills in Colorado's high country. For my part, I ride my mountain bike hard and wanted an e-bike that could take whatever I chose to throw at it. I also love the mountains and needed a bike that could do some serious climbing.

If you can't see the difference between an Optibike and the rest of the field, might I suggest taking your best bike to the base of the Pike's peak road and see how far you get. An Optibike rider made the 19 mile, 7000' elevation gain trip to the summit in 1:40.

Regarding the price, let me say this: The initial cost is often forgotten after you have owned something you love for a while and plan to keep using; while the cost of a bargain that did not meet your needs may remain a bitter memory.
