All three road bikes receive their power from Yamaha’s PWSeries SE motor that comes with four levels of support: ECO+, ECO, STANDARD, and HIGH. The mid-drive motor supplies a maximum of 70 Nm (52 ft-lbs) of torque and cadence support up to 110 rpm. The motors are designed to provide assistance up to 20 mph (32 km/h). Any faster, and it’s all you providing the power.
In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.
“Yamaha’s power assist motors provide the purest, most natural assist feel thanks in part to Yamaha’s Triple Sensor System that has been exclusively optimized for Yamaha’s U.S. power assist bikes. Through the Triple Sensor System, thousands of times per second, frictionless sensors measure the rider’s pedal-torque, bicycle speed, and crank arm cadence with tremendous precision.”
E-bikes are one of the latest ways technology is infiltrating the fitness market. Although they may seem techy and confusing at first, they really are just regular bicycles with a little extra boost. To test one, ask your local bike shop to demo a model they have available (pro tip: If a bike shop won't let you demo, don't shop there). Just getting on one will definitely help you understand how an e-bike works and how one might work for your lifestyle and goals.
From the tropics to the polar caps, Stark Drive is designed to handle a broad range of temperature conditions with a ruggedized frame and high quality battery pack as well as all terrain tires (standard) or even our fat tire model. Take Stark Drive with you wherever you go. When Designing Stark Drive in Stockholm Sweden we were very conscious of the fact that weather effects battery life on your electric bike so we designed our electric bike with this in mind.

The other thing to consider is that this is a Kickstarter project, so you aren’t directly purchasing from the company, but rather “backing the project” in exchange for a bike. Technically, Stark Drive, or any Kickstarter creator, could cut and run with the money, leaving their backers without legal recourse. In this case though, Stark Drive has already run a successful crowdfunding campaign for their previous bike and demonstrated their ability to deliver, so this is probably at least somewhat safer than a brand new Kickstarter start-up.
In the year 1885, a British man named J.K. Stanley introduced what can fairly be described as the first modern bicycle. His Rover bike had wheels of equal size in the front and back and used a chain connecting the pedals and the rear wheel as a propulsion system. It was often marketed as a safety bike in contrast with the unstable Penny Farthing, and was a smashing success. The company went on to develop motorcycles and automobiles, remaining in business until the year 2005.
We are making room for all the new models of Pedego electric bikes soon to arrive. Owners Jean & Terry of Pedego Denver electric bikes have always had the largest electric bike store in Colorado along with the largest selection of Pedego Bike models & colors. So with the unveiling of several new models & colors at the recent Pedego Dealer Conference in Newport Beach, CA. We realized that we needed more room to display them, so we decided to expand and even moved walls to do so. We now have over 5,000 square feet making Pedego Denver one of the largest showrooms in the nation and a true Mega Showroom. The new space also includes a new Pedego experience...

Fat E-Trike from Sun and E-BikeKit™ at Interbike 2014 Fat bikes and electric bikes were all the rage this year at interbike in Las Vegas. It seemed almost every bike vendor at the show has at least one fat bike model in their booth this year. On top of the fats were the electric bikes. And I think it goes without saying that nobody wants to actually pedal a fat...
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.
For an overview of Stark Drive Electric Bike, its features and our story click above. Our passion for biking and our determination to take electric bikes mainstream have driven us to create the world’s most affordable electric bike. As technology improves, so will Stark Drive with the caveat that we will always offer the most affordable electric bikes in the world.
Patriot DreamE has motor cut-off brake levers and lighted battery indicator on the throttle. Some electric bikes have small tires which perform best on smooth streets. The DreamE has full size, 26" wheels for a safe and comfortable ride. Patriot customers have a choice of color, frame size (standard or small), seat style (contour or velo), motor power (350 / 500 / 750 watts), and battery chemistry (LFP).
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.
However, Emu sells a little foldable number if that's your bag. The Emu Crossbar is for  town commuters that require a sweet ride that's backed up by solid Shimano Nexus hub gears and Tektro brakes, which are adequate if not the best on the market. Riding is smooth and easy, with the crank moving sensor doing its best to iron out any gaps in power delivery.
Standard front suspension is the 7” conventional single crown forks. With 2 dials to adjust compression and rebound adjustment and air adjustment for preload, these forks are light weight and versatile enough for most situations. For heavier or more adventurous riders, the forks can be upgraded. The rear suspension is adjustable for casual every day riding or more aggressive off road environments.
What a treat to do business with the folks at Hill Topper. I now have two commuter units one in Idaho and one in Denver my average ride is 25 to 35 miles. I have been riding for about 15 years but being the age of 80 I needed a little help the past few years. I researched electric bikes a few years ago even rode a couple here in Denver but I wanted my own personal look and feel. So about five years ago I found Hill Toppers. What a treat first the units are the best but that is part of the good part the people at Hill Toppers are the very best to work with and enjoy. I had to have a knee replacement last July well thank god for my bike it was the best therapy I could ask for. When in Idaho I get to ride along the Snake river what a treat knowing that I have this unit to help if the wind or rain shows up. When in Denver I cover a lot of area as they have wonderful bike trails all over the area. I ride all of the downtown area and the Cherry Creek dam up and over it takes some effort to get that done but with the help of Hill topper it is a beautiful ride up and overlooking the whole of Colorado. Thank you Andrew,Charles,Sam,Mark.
Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can rank you up to 28mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. Don't expect it to feel like a 16lb race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps the it nimble and agile at high speed.
