The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.

Update: Well I've had an opportunity to take the bike on some longer trips now 10 miles back and forth a few times, and the bike performed well, so I am raising my rating to 4 stars. I got a larger seat and raised the angle of the handle bars and it is more comfortable to ride than it was, but still a bit awkward for someone of my size. I've been leaving the bike charging all the time I'm not using it and this seemed to make a big difference with the indicator light not coming on as soon, and the biggest difference is made by me riding the bike the way it was meant to be ridden, ie: pedaling, I was treating it more like a scooter and just staying on the throttle before, but if you use it as a peddle assist bike, the way it's meant to be ridden it performs quite well. The bike is not great going up hills and you still have to work but it does make hills a lot easier. It is also frustrating not having more gears, you basically just leave the bike in 6 gear all the time, and peddle when you can ie: when your slow enough you can peddle. I have no problem with the weight of the bike and it is solid and well built and it will work for my purposes, fortunately the town I live in is only about 5 miles end to end so I don't need the bike to be able to go super long distances, and fortunately I don't mind peddling some, so I don't mind the bike being a peddle assist bike and not a more scooter type. One other gripe I do have is the bike does not have the standard holes to mount a back rack to, one of the main reasons I got this bike was to carry groceries and stuff more easily, so I'm disappointed that it will be difficult for me to mount a rack to, but I'm sure a front basket would work. Anyway, 4 stars, I like it, the price is great, it's well constructed, you will have a hard time finding an electric bike of this quality at this price, but it is not without a little sacrifice.
Wide tyres are an absolute must on an eMTB. They offer more traction, provide extra comfort, increase stability, and they simply look cooler. Tyres with a width of 2.5″ – 2.8″ have proven to be the ideal size. The performance of the MAXXIS Minion tyres is particularly impressive; they provide the best grip and stability. To get the best performance, tyres should be ridden at approx. 1.2 – 1.6 bar air pressure.

The Spectral:ON 7.0 helps you to try new ways, to shift boundaries and to sit in the saddle more often. The Enduro configuration with rigid RockShox Lyrik RC suspension fork and RockShox Deluxe R shocks tames the roughest trails. The E-MTB-specific DT Swiss H1700 Spline wheels are fitted with robust Maxxis Minion tyres that offer maximum grip and control downhill. The Shimano Zee brakes from the freeride sector with 200 mm large brake discs at the front and rear are very powerful - there is no more control and safety in this class. The 165 mm short cranks guarantee the best possible ground clearance. The Kind Shock Lev Integra SI Vario seat post can be lowered at the push of a button when it gets steep. All in all, the Spectral:ON 7.0 is your ticket to trails that otherwise might not have been accessible.
The quality of electric mountain bikes is changing dramatically. We set out to find the best ones you can buy today. After looking at 15 models, we narrowed it down to four in the $5,000-$5,500 price range. We then took to the trails. Over the course of several months, our team of testers rode these e-MTB's for thousands of miles and hundreds of hours to find out how each model performs on the trail, which one has the longest range, the most power, and most user-friendly controls. We rode these bikes hard, scrutinizing every aspect of their performance, exposing the strengths and weaknesses of each. We present our findings here in this detailed comparative review to help you find the model that's right for you.

By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]
