The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
Last year, the Trek Powerfly 9 LT was one of the only ebikes with geometry and handling that came close to a modern enduro bike. For 2018, Trek has built on that winning formula with new frame. It’s lowered the battery in the downtube, while adding a stiffer Fox 36 fork, more powerful SRAM RE brakes and a stronger Bontrager wheelset. All welcome improvements to a really capable bike. The price has also crept up to reflect the changes. The biggest transformation however, is that Rocky Mountain has raised the ebike bar to a new high with the Altitude Powerplay.
For those who know the brand, Ducati makes lust-inspiring road motorcycles, covering the range from scramblers to naked bikes to sport bikes. They’ve topped podiums globally, appeared in too many movies to name, and in some cases have ended on display in art galleries. But like everyone in the motorcycle business, the company is challenged by global changes and is looking to capitalize on its valuable brand. Likely it was challenged to by its corporate overlords, as the Ducati company was acquired by Audi and hence VW in 2012.

It seems everyone prefers both Juiced and RadCity E-Bikes. I am having a tough time choosing between two. I currently have a mountain bike and want something new just to kick back and cruise around on. I will not be daily commuting, but will be riding weeknights and weekends, so comfort is key. It looks like both will have deals for Black Friday or Cyber Monday. $999 for the Juiced OceanCurrent and $1299 for the RadCity.
Mountain bikes have come a long way since the 80s. Rock Shox showed up and eventually everyone had a hardtail bike. Then came dual-suspension bikes for all sorts of riding styles. My choice was a cross-country bike so I could climb fast and descend fast without the need for big air. Brakes have gone from simple calipers, to grippy Shimano V-Brakes, to bomber hydraulic disk brakes. While all this was going on street-focused eBikes were evolving too. It should be no shock that the technologies would merge to create eMTBs. A lot of people who were part of the mountain biking revolution in the 80s are getting older and eBikes allow them to continue the sport they love later in life. Whether it’s riders dealing with health issues or injuries, or simply just getting older, the emergence of eMTBs makes total sense.
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.
Direct-to-consumer Italian brand Thok’s MIG bike has reviewers falling at its feet. Why? It simply offers a superb package – its geometry and construction are as on-the-ball as its choice of Shimano motor, battery placement – giving low centre of gravity – and quality build kit. At under £4k, the MIG is great value too (there is also a pricier MIG R, featuring upgraded components). Thok knows its stuff, which is hardly surprising when you look at its founder. Former champion downhill racer Stefano Migliorini understands what makes a good bike, and he personally leads the charge on bike development at Thok.
The Espin is powered by a 350-watt motor that’s rated for trips up to 50 miles (depending on the terrain and assist level). Once depleted, the battery fully charges in roughly five hours. Thankfully, Espin makes it easy to remove the battery, allowing you to quickly recharge it at home or in the office between trips. A backlit LCD control hub displays your basic metrics and battery life while in transit and LED headlights add a touch of light when needed.
The Pedego Ridge Rider allows me to get the level of workout I desire, see and spend more time outdoors by riding 2-5 times the distance I would on a manual pedal bike, ride more often (almost every day), and enjoy my rides to the fullest. It helps my neuropathy, I have less pain. It helps control my diabetic sugar levels. It also is very therapeutic mentally. I’m the healthiest I’ve been in years.
The LT or long travel line that Haibike is one of the most interesting developments in electric mountain biking in quite some time. I’ve chosen the FullSeven LT 4.0 because I wanted to show you another quality, low-cost option. The FullSeven line is built a little less aggressively than the AllMtn series, but still functions as a great all-around mountain bike for those riders who want to hit fire roads, and maybe the occasional single-track trail. The coolest thing about the LT line is that it costs exactly the same as the standard FullSeven line that comes with 120mm of travel. You can upgrade to 150mm on any FullSeven bike for no extra cost.
Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
I really wanted to love this bike, I've only had it a few days, and it's probably too soon for a review, but I can see some issues with the bike. I'll start with the good, it was here 2 days after I ordered it which was amazingly fast shipping, the bike was easy to assemble, very sturdy and high quality looking and feeling, and even came with a nice tool set for assembly and a bell and water bottle, pretty good saddle, and I was very happy with the price, if it performs as I hope it will. Now the bad, as soon as I get a quarter mile from the house my battery indicator light goes from green to yellow, that is way too soon for the battery on a bike with this alleged range to be at "half life?". I have read in other reviews many have the same issue and say that it is just "inaccurate " and to "not pay attention to that" but it is disconcerting to me. Also the bike does not have the power I was expecting, it is truly a "peddle assist" bike, and not a throttler, the bike basically wants you to peddle and works best as you peddle, in fact the motor actually cuts on and off based on you peddling, in addition to cutting on with throttle, don't get me wrong it will power through on throttle alone on a flat surface pretty well, but if you expect not to do much peddling at all, this is not the bike for you. The fit of the bike isn't great for me, I am 6'2 and the fit for me is a bit awkward, ie: the bike is a bit small for me, anyone my height or taller may want to look at other options, and I can't raise the handle bars at all I don't think, although I believe you can change the angle of them. I've only taken it for 3 short rides as of yet and I was reasonably satisfied with the bikes response and power for my needs on these short trips, but I will have to take a few longer rides before I can give a more complete opinion. The bike is an eye catcher and I see people staring at it everywhere which is cool, I will update as long as I continue to own the bike, but I'm still a bit on the fence about it.
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. 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.
