E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
The first step in deciding which Electric Bike is for you is to determine the right style of bike. We have a full range of styles, including, Mountain Electric Bikes, Comfort E-bikes, Commuting E-bikes, Fat Tire Ebikes and even folding bikes. From their, you'll choose the motor size. We offer motor sizes from 100 Watts all the way up to 6000 Watts!
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider. Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes, have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains. The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
FRAME GEOMETRY EcoBike electric bikes have been specially designed with the daily commuter in mind. The frame is constructed from a high-strength, lightweight 6061 aluminum alloy that maximizes safety and durability. The enhanced frame design features comfort ergo-geometry that is more upright than a traditional mountain or road bike. Every EcoBike electric bike is outfitted with suspension on both front forks (except Vatavio) and seat post to deliver a smoother ride.
To help the rider find the perfect fit, the stem is adjustable. The bike also boasts dynamo powered lights alongside hydraulic disc brakes. The bike will suit riders from 4 ft 10 to 6 ft 5, and also integrates with a child seat. The total weight is 21.8kg, making it admittedly a fairly hefty folder – but that’s fairly uniform across electric versions.
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.
It will be of little surprise to learn that the Hanebrink all-terrain vehicle was designed by six time Mountain Bike national class champion and former U.S. National Team member Dan Hanebrink. It's based on 1993's Extreme Terrain fat tire pedal bike and is made to order at the Fortune Hanebrink workshop at Big Bear Lake, California. Echoing the philosophy of many electric assist bicycle makers, Hanebrink says: "We are not trying to replace standard bicycles, we want to replace cars and trucks."
EcoBike offers three e-bike models. The Vatavio fold-and-carry electric bike (pictured above) is innovative and well constructed. The Elegance (pictured below) is a classic design with step-through frame, offering an easy, comfortable ride. The AdventureÂ’s revolutionary frame design allows for true versatility, going from the pavement to mountain trails with ease.
Irvine, Calif. – As eBikes transform into a "lifestyle product," smart aesthetics and attractive design play an increasingly important role. That’s why Bosch eBike Systems is setting the pace: for Model Year 2018, presenting the PowerTube 500, a battery which can be integrated into the frame of the bicycle. The PowerTube 500 combines modern design with first class Bosch technology for eBikers who prefer a clean and timeless look.
The F1-trained engineers at William Advanced Engineering assisted with the electrical parts and the result is a 250W motor that provides pedal assistance via the front hub – which is a highly unusual approach – drawing power from a 300Wh battery pack that sits in a bag and goes on the front where the Brompton luggage rack would normally sit. You can also opt for a larger bag that holds both the battery and your spare suit or laptop or whatever.
At speed the E proved a stable and neutral ride, the motor engaged in good time and there was a reasonable amount of assist (the amount of motor assist is adjustable via a Bluetooth app up to 25kmph or 15.5mph). Charging of the in-hub battery is possible via a neat hollow charging bolt on the drive-side of the rear wheel. The Cooper E is one for retro-futurists and people who want others to say, "No way that’s an electric bike!"
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.
