Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike. The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
"[My Bike Friday] represents the pinnacle of 31 years of cycling for me. It is incredibly well designed and features excellent, predictable road manners consistent with high end road bikes. Steering response is very quick due to the lack of gyroscopic force in the front end. Low wheel mass makes for excellent acceleration and climbing. A delight to ride and own."
The folding bike may be the most convenient mode of transportation on two wheels: It can get you from point A to point B just as readily as a full-size bike, but you can stash it in a car trunk, tuck it under a desk, or store it in a closet. To suss out which folding bike does it all best for most commuter riders, we pedaled and shifted, folded and unfolded, and carried and maneuvered 11 popular models from eight manufacturers. After our 60-plus hours of research and testing, the well-designed Dahon Mariner D8 edged to the front of the pack, combining a comfortable ride and easy folding with good-quality components, all for a reasonable price.
Your embark is more than a bike – it's a healthy alternative to traffic, hills, parking and sweat. 65% of riders use their eBike to replace their car. 66% said that they preferred an eBike because of hilly terrain near work or home. Nearly 75% rode their eBike to different destinations than their standard bike. The Embark brings your destinations closer and expands your world - all with simplicity and reliability.
But as a commuter vehicle, the Metro just lacks a few crucial details. There are no eyelets to attach a rear or front rack, so your storage options are limited to racks that clamp onto the seat post, or baskets that attach to the handlebars. Both of these options have much lower weight limits than a traditional rear rack. Your options for fenders (a necessity for foul-weather commuters) are limited, too, since the wheel forks don't have very much clearance.
Folding bikes have long been popular among commuters who need to store their bicycle in a small space at home or in the office. Thanks to their small folded size, they are easy to get onto trains and buses, or even a taxi. With the rise in popularity of electric bikes in recent years, it is no surprise that folding electric bikes have come onto the market as well.
A hinge in the frame may allow the rear triangle and wheel to be folded down and flipped forward, under the main frame tube, as in the Bike Friday, Brompton Mezzo Folder, and Swift Folder. Such a flip hinge may be combined with a folding front fork, as in the Birdy. Swing and flip hinges may be combined on the same frame, as in the Brompton Mezzo Folder and Dahon, which use a folding steering column. Folding mechanisms typically involve latches and quick releases, which affect the speed of the fold/unfold. Bike Friday offers a model, the Tikit, featuring a cable-activated folding mechanism requiring no quick releases or latches, for increased folding speed.
Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.
Foldable bikes are a versatile and often-overlooked cycling option. Maybe your studio apartment has limited storage place, or perhaps your commute involves a train, several staircases, and a crowded elevator. A foldable bike is a cycling problem-solver and a bundle of fun packed into a tiny package. From lightweight singlespeeds and cruisers, to a fully-capable cargo bike, there is likely a foldable bike out there to suit your cycling needs. Here are some of our favorites.
The Ancheer folding electric mountain bike does have a few weird quirks. The first is the handlebar mounted battery. It saves space for the folding mechanism, but looks odd. Fortunately it has very little effect on handling because it is mounted so close the head tube’s pivot point. It does raise the center of gravity of the bike a bit, but the difference is small compared to how much you raise the bike’s center of gravity.
