We ran the C330 almost entirely in its speediest Turbo setting, switching back to Eco or Tour in heavy traffic for a more predictable assistance weaving between cars. Crucially, the display also displays how much assistance you’re getting as well as your speed, trip distance, etc. We used this to ease-back effort and stay in a light power sweet-spot, arriving at WIRED’s HQ without breaking a sweat.
Prices have rarely been this low, with perhaps only the Xiaomi Himo electric bike that we covered costing less, at $261. Of course that e-bike is only available in China for now, unlike the Stark Drive Mini that can ship to the US, albeit for an extra $200 shipping fee. (Spoiler alert: I was able to procure a Xiaomi Himo via a friend in China, and assuming I can get it into the country, we’ll have that review coming up.)
Is it worth $1700? I’ll let you be the judge. I don’t have a lot of experience with commuter ebikes so I don’t know how it compares. I do know that most of the ebike conversions I’ve seen look like science experiments. The Buffalo could pass for a normal bike, and look a little more accessible to a first time ebike user. So, although I’m not planning on riding this, I am planning on using it. So I’ll keep it around for a while and let you guys know what I think long term.
This is the Freway Buffalo. It’s an ebike. I couldn’t say no to a free ebike to play around on, so we’re gonna have some fun with this thing for sure. It’s not a high end ebike like the Specialized Turbo Levo, but it only costs 1700 bucks whereas the Turbo Levo costs as much as a car. Although it’s marketed as a mountain bike, I’d put it in the commuter category. It’s got a big cushy seat, a really long stem, and those antler things on the handlebars. I’m not obligated to give you guys anything but the truth, so let’s put this thing together and take an objective look at it. First, let’s cruise on over to Freway’s website.

E-bikes can be a useful part of cardiac rehabilitation programmes, since health professionals will often recommend a stationary bike be used in the early stages of these. Exercise-based cardiac rehabilitation programmes can reduce deaths in people with coronary heart disease by around 27%;[55] and a patient may feel safer progressing from stationary bikes to e-bikes.[56] They require less cardiac exertion for those who have experienced heart problems.[57]
The downside to this mountain-bike build and specification is obviously the weight, at 24.5kg the Trekking feels heavier than the other bikes on test, and rightly bills itself as suitable for heavier riders, too. As with the other bikes here, this is only really a problem for smaller riders, or riders needing to take the bike up or down steps regularly. With its bomb-proof build, full guards and heavy-duty rack, the Haibike is the perfect choice for a burly rider or for doomsday preppers, ready to out ride the apocalypse.

After suffering a back injury and returning home as a disabled combat veteran, Chris found himself unable to exercise the way he had in the past. It was particularly discouraging to be kept from riding his beloved bicycles. Rather than dwell on his misfortune, he decided to search for viable alternatives. It wasn’t long before he settled on his first electric-assisted bike. His passion for bicycles was reinvigorated and he realized he had to share it with the world.

You should be extra aware about your local regulations as in many countries an L1e-A certified bike needs to be registered and insured (be sure to consult your local laws and rules) and with registration comes the security that the bike can be tracked if it is stolen or misplaced. This approval that we have received is European Union wide and even those countries that are not part of the EU but rather EEA do adopt similar regulations in order to keep the market common but you will need to consult with your authorities. We will detail more about the registration process in an upcoming blog post but if you have any questions you can email us and we will respond in kind.
The Soho is one of Coboc’s four single-speed pedal-assist bikes. The bikes are differentiated with finishing kit - handlebar style, bar-tape, saddle and paint finish. With a retro / bespoke styling with Bullhorn bars, Brooks fabric-tape and Cambium saddle and brushed aluminium frame, the Coboc is an e-bike for riders who don’t want to look like they’re riding an e-bike. The ONE Soho is for a rider that doesn’t want gears either.
Electric bikes or ebikes, widely popular in Europe and China, are steadily making their ascent in the U.S. bike market. Erik Saltvold, founder and owner of ERIK’s Bike Shop, a Midwest-based chain for bike sales and repairs, says the ebike is the fastest-growing specialty bike in the industry. Last October, market research company NPD Group reported that electric bike sales had grown 95 percent in the 12 months ending in July 2017, with sales totaling nearly $65 million.
Over the years our lineup has grown, and as a result, the offering has become more complicated than it needs to be. Specifically, this year we introduced a 500w geared motor option to the lineup and that has created some redundancy. Before outlining changes, we would like to ensure everyone that we will be stocking enough inventory of previously sold parts for a long enough time to ensure all warranties...
Kalkhoff's electric-assist bicycles start with the same high-quality, sleekly designed bikes that Kalkhoff has been developing for 90 years. A state-of-the-art, brushless, centrally-located motor provides a smooth, predictable power-assist directly to the drive train. Kalkhoff e-bikes come fully-equipped with a variety of features to ensure that your commute, shopping trip, or outing is safe, comfortable and fun.
Bicycles have long been one of the most popular modes of transportation and, in a time where environmental friendless and health are top of mind, the popularity of bicycles shows no signs of slowing down. For many bicycle enthusiasts, an electric bike is the best of both worlds (get where you're going faster and not winded) and with a range of choices and designs available, we've helped narrow down the best models on the market today.

The Nuvinci hub system is the best geared hub that I have ever used. There is literally no maintenance to be done on this drivetrain. I’d recommend buying it with the Gates Carbon belt because you’ll never run into issues like the chain falling off. You operate the Nuvinci system with a grip shifter and can of course shift even when you’re not moving.

The patented "dual power system" allows for power-on-demand riding (limited to no pedaling), with a top speed of 20 mph and a range of up to 20 miles. Feel like pedaling? Just switch to pedal-assist mode and let the state-of-the-art torque sensor augment your pedaling efforts with motor assistance. Pedal-assist mode allows for 45+ mile range. Charging is easy with their patented removable battery system. Simply unlock the internal battery storage case on the frame, remove the battery, and charge up with any 115V power outlet (onboard charging is also available).

Azalea Festival. For the past year, students in CFCC’s mechanical engineering program have been hard...

One reason for doing so is the way it is powered, which works in a manner that would be familiar to someone accustomed to a manual transmission car. Like a car, you start in a low gear and work your way up as you gain speed. Since the motor runs through your transmission as opposed to applying power directly to the axle, the gear you’re in really matters. The importance of gearing connects you much more to the road and the terrain, which means you are a more active rider than when using throttle-controlled electric bikes.
As far as battery life goes, e-bikes get their juice from a rechargeable battery usually located on or integrated into the frame, and many are removable, so you can power up wherever it’s convenient. The length of your ride and how often you use the bike will determine how frequently you have to charge up. “An e-bike battery can last anywhere from 15 to 60 miles depending on the terrain, how much assist you select, and the rider’s weight, among other factors,” says Jonathan Weinert, North American sales and marketing manager for Bosch eBike Systems. “With a dual battery [like the one Bosch has], you can double that range [around 20 to 120 miles], so it’s very feasible to commute for a week without charging.”
Pedal Assist Electric Bikes, also known as "E-bikes," are bicycles that have an electric motor to assist riders. The motor is powered by a battery and only assists the cyclist when he/she is pedaling. Electric bikes come in many different styles including commuter, recreational, step-thru with low-entry frames, cargo and mountain. They all have one thing in common: e-bikes are very simple to ride – if you can ride a bike you can ride an electric bike!
I think this is a super interesting bike. I like seeing IZIP stepping into the world of Brose motors. Brose bikes always look clean and refined because of the battery integration. This bike is a pretty great value for what you get. Totally integrated lights, rear rack, fenders, and plus sized tires are all great to have. I wish it had a dual chainring in the front, but you can always add one on a Brose motor.

Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]

For many bikes, battery range is more important that total power (because they're all pretty powerful). You want a bike that delivers a range long enough for your rides at the power levels you want. Most e-bikes will have three to five levels of assist kicking in anywhere from 25 percent of you pedal power to 200 percent boost. Consider how fast the battery takes to recharge, especially if you'll be using your bike for long commutes.
