This bike is named the GSD because with it you can Get Stuff Done. Twenty-inch wheels keep the center of gravity low so heavy payloads—it's rated up to 400lbs—are easy to balance and a short (for a cargo bike) 70-inch wheelbase, similar to a standard single bike, make the GSD easy to maneuver. Designed with the urban commuter in mind, the bike can easily break down to 60 percent of its original size to fit into the back of a car and the rear rack doubles as a stand that allows it to stand upright to minimize space inside tight apartments. Put two child seats on the back and take the family along, or drop the seat and let you kid take the bike out himself—anyone from 4'10" to 6'5" can ride this bike. Last but not least, the GSD gives you the option of adding a second battery to extend your range up to about 150 miles on a single charge.
This bike is designed for quick handling and high speeds, and not for comfort per se. The Focus is all about form following function. This is both good and bad: you have a bike that is sleek, powerful and nimble, but you also are going to be crouched over the front wheel for better control, gripping no-nonsense grips and riding a saddle meant for performance, not cruising.
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.
Certainly not for the entry-level e-bike buyer, those who need to strap cargo to their back now have a new option with the Riese & Muller Load option, with full cargo space on the front of the bike. While over $6,000, the full-suspension bike has adjustability to allow for differing loads. Safety features include LED headlights and premium components abound.
Twice the speed - with half the effort, Optibike has the power. On a test ride in Boulder Colorado, a fit road cyclist was able to climb the notorious Old Stage Road at 10 MPH sitting down with an easy spin on the Optibike. On his ultra light road bike, he had to stand and grind all the way to go 5 mph!!! Twice the speed - half the effort, Optibike has the power.
A vertical bike rack for your car that can fit up to six bikes at once! Works with all different sizes and types of bikes... even fat tire, kids, recumbents and tricycles. Unlike many horizontal hang-style racks this thing can accommodate step-thru and wave bike frames without the need for a crossbar adapter, the rack folds down for easy storage...
Spec-wise, this thing is tricked out. You’ve got the option to go with Suntour AION suspension or Fox Float suspension. The drivetrain is Shimano Deore XT. Same with the hydraulic disc brakes. The bike also comes with an ABUS Big Bordo folding lock that is keyed for both the batteries and the lock. Super convenient. There’s also loads of other options within the Delite line. Nuvinci and Rohloff drivetrains, 20mph and 28mph motors, standard and plus tires. You get the idea. Lot to choose from.
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.
After you decide which style of e-bike you want, consider the class. In the US, there are three classes defined by the type of assist and how fast the motor will propel you. Most electric bikes sold are class 1 or 3. Class 1 bikes have a motor (max 750w) that assists while you're pedaling, up to 20 mph. Class 3, also known as “speed pedelec” can also have up to a 750w motor, but it can assist you up to 28mph. Both of those are allowed in most states and cities without license. Class 2 have throttles that don't require you to pedal to get a boost. They're allowed on most streets, bike lanes, and paths, but less popular than the other classes and not covered much here (because we still love to pedal and the greater distances pedal assist bikes can cover).
