Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don't require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.

Electric Bikes Are Now Legal on Pennsylvania Roadways! Breaking News... According to the Bicycle Access Council of PA in their November 2014 News and Digest, Electric-Assist bicycles are now legal on Pennsylvania roadways as part of Act 154. "Electric-Assist bicycles are now legal on Pennsylvania roadways as part of Act 154. In a convoluted way since first introduced in 2010, a last minute amendment was introduced by Representative Kevin Schreiber (D-95) with...

The Spectral:ON is our most challenging development project to date. With the focus on the essentials, it was our clear goal to design an E-MTB that rides like the perfect trail bike. The result is already award-winning: modern trail geometry, wheel concept with 29/27.5" wheels front and rear, plus Shimano's powerful Steps E8000 drive. With the support of the engine, Spectral:ON expands your horizons: more trails per hour, trying out new ways and pushing the boundaries. You master even steep, technical climbs playfully and enjoy the agile handling and the outstanding smoothness in fast passages downhill. Space for bottle holder, geometry adjustment and lightning-fast battery change? Standard! We've taken every detail into account to give you the ultimate E-MTB driving experience.

If exploration is the new black, then the Ariel is a bike dressed for adventure. Versatile and reliable, hit the road with purpose as you chase down your fitness goals, then satisfy your inner explorer as you veer onto the dirt with confidence. Its Women’s Custom tuned suspension and Multi-Circuit Damping fork turn rough to smooth, while giving you more control as you explore your world on two wheels.

I know that this topic is new and still contentious, but the community needs to be talking about it because it isn’t going away. The weather up here in Seattle is rainy and cold (no surprise there), so I haven’t ridden my new eBike except around the block to make sure it worked. I can’t wait to hit the trails (legally or illegally). Expect a follow up comparing the eMTB to my other mountain bikes both in how it performs and the feeling I get from riding it. I never thought I would be riding an eMTB, so trust me, I won’t hold back.
This is a question the designers and engineers of the FOCUS and BULLS bikes of this group test asked themselves. Instead of speccing them with the standard 500 Wh batteries, both have developed a sophisticated alternative. The idea: instead of riding around with unnecessarily large batteries and unnecessary weight on short tours, they integrated a smaller 375 Wh or 378 Wh battery into the bike. If you don’t have enough power for long loops, you can double the range of both bikes with an additional battery for up to a full 750 Wh. While the second battery is mounted in the front triangle of the FOCUS, it disappears sideways in the downtube of the BULLS. In practice, you’ll need the second battery relatively often with both bikes, and in either case, you should consider the additional € 499 investment in a second battery pack when you buy the bike.
Many years of experience have clearly shown that it isn’t possible to make a universal and realistic estimate of an ebike’s range. The range of an eMTB depends on countless factors such as the support level, terrain, rider weight, environmental conditions, and cadence. Those who demand a lot of power from the motor consume a lot of electricity. If you want to travel far, you’ll have to save battery power.

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.
It’s hard to ignore the growing popularity of electric bikes. Commuters and hybrid riders have already embraced the technology, but what about when it comes to mountain shredders? MTB fans are certainly beginning to realise the benefits of electric – an electric mountain bike can give you all the thrills you want from a normal MTB but with the extra power you need to get back to the top and give the trail another go.
E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.
