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.
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.
It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
Elon Musk had a good 2018, at least in retrospect. Coming out of production hell, Tesla’s Model 3 is now the #1 selling car in the USA by revenue, along with various other signifiers that Tesla is now a real, high-volume car manufacturer. Tesla itself declared a $300 million USD profit for Q3, delighting the stock market and its investors, if not the many shorters who continue to lose money and credibility.
While the first functional battery was developed in the year 1800 by Italian physicist Alessandro Volta, a practical battery would not be seen for several decades yet. By the end of the 19th century, practical and portable batteries were more widely available, this finally freeing the electric motor to be used in a wide new array of applications. It might come as a surprise, but the electric motor, battery, and a bicycle were first paired as far back as the 1890s. It would be approximately 100 years later that electric bicycle development finally entered the mainstream, but the technology and concept behind the electric bike were all in place generations ago.
And so in 2015 it partnered with Bianchi, another fabled Italian brand, one which has been building racing and road bicycles since 1885. They introduced a Ducati-branded series of bicycles, engineered by Bianchi. Now the company has included electric bicycles for every adult purpose. It’s possible that at this point, Ducati is selling more bicycles with electric motors than it is motorcycles globally. They are certainly at a better price point, while not being cheap by any means, with the pictured TT Evo S roughly a quarter of the price of a Ducati Monster Anniversario edition.
For those who may be unfamiliar, Burning Man is an annual gathering in the Black Rock Desert of Black Rock City, Nevada. The event, which began in 1986, spans from the last Sunday in August to the first Monday in September. There are no corporate sponsorships, advertisements, or entertainment at the event. Individual participation is what's key to making the event special and memorable. Although the participants are given a...
…but currently offer only very few advantages, such as a cleaner design and the option to mount a bottle cage in a front triangle. If you want to take a spare battery in your backpack, you will have to struggle with the larger dimensions of the integrated batteries, or you won’t have the possibility to take one with you at all. Depending on the integration, handling the integrated rechargeable battery (e.g. the on-button for Shimano-Intube) can be awkward. Also, the longer battery results in a higher centre of gravity. The fact is that there are good reasons for continuing to use a standard external battery.
eMTBs appeal to an extremely broad target group: some use their eMTB for daily commuting, others for after-work or weekend rides on maintained gravel roads, and others plan to do an electrified alpine traverse or even an action-packed visit to the bike park. The good news is that many eMTBs are jacks of all trades, covering a very wide range of uses. Others, unfortunately, may disappoint with poor spec or nervous handling.
