Electric bikes offer the chance for those with low lung capacity (asthma sufferers, for example), or a reduced fitness level to get out and enjoy the countryside. Even those who are moderately fit can appreciate some assistance when going up hills.
If you’re e-bike-curious and want to see how one will fit into your life or just don’t have the up-front capital to buy an e-bike, Riide has a solution: rent an e-bike by the month. The company only one eponymous model. It’s lighter than most at around 40 pounds, can go up to 20 miles per hour, and has a battery charge that lasts 25 miles, while taking only two hours to re-charge. It also comes in badass black. Renting the Riide gives you your own Riide electric bike, theft insurance, a charger and lock, unlimited maintenance (in Washington, DC and San Francisco, CA only, sadly), but it does involve a 12-month commitment. After two years, you can upgrade to the latest model and keep renting, or stop paying rent and own the Riide.

Battery: 36V 8AH lithium battery. Power: 250W. The frame folds via a 2 part locking mechanism which ensures the catch safely remains locked when the bike is in use and can be operated with one hand for a smooth folding action.
Electric bikes (e-bikes) are very similar to regular bikes, only more fun! An e-bike has a motor and a battery that provides assistance to help the rider go further and faster. While still getting an effective work-out, you can ride up tough hills easily, enjoy long distances and have a faster commute. E-bikes are also environmentally friendly! With an e-bike, you choose your speed and assist, putting you in control of your entire ride.
I’m not kidding. If you are around others going slow, you go slow too as you pass them. When you are not around others moving slow, you can go faster. So what are you doing? A mom and three young kids, and a dog are out on the going 5 mph, and you fly past them at 35 mph? Is that what you tell me you are doing? You should have your bike taken away from you if that’s what you are doing. And if you have a driver’s license, you should have it taken away as well until you become mature enough to operate such a dangerous vehicle.

HR-727 amended the Consumer Product Safety Act, which falls under Title 15 of the United States Code, which is overall entitled “Commerce and Trade” – so it’s very clear from the context that the federal definition of “low speed electric bicycle” is intended to pertain only to commerce and trade (i.e., importing and selling) of e-bikes. HR-727 was intended to place e-bikes under the jurisdiction of the Consumer Product Safety Commission when it comes to establishing safety requirements for e-bikes imported and sold in the U.S. (as opposed to DOT or NHTSA, which handle such requirements for motor vehicles like cars and trucks). Federal law says nothing about where and how e-bikes may be ridden, thus allowing states and local jurisdictions to set their own rules.
Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles, so they are not subject to the more stringent laws regarding their certification and operation, unlike the more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated as a specific vehicle type in many areas of legal jurisdiction.
Photo: Zap Electric’s power-assist kit turns a conventional bike into an electric one. There’s a bolt-on DC electric motor (weighing just over 3kg or 7lb) just above the back wheel, behind the police officer’s foot, pressing against the tire and driving it by simple friction. The motor’s powered by a compact lead-acid battery (weighing about 5.5 kg or 12 lb) inside a protective nylon bag. This kit adds quite bit of weight to the bike, but gives extra range and speed when needed. Photo taken in Santa Rosa, California courtesy of US DOE/NREL.

Build Your Own Electric Bicycle by Matthew Slinn. TAB Green Guru Guides/McGraw-Hill, 2010. Introduces electric bikes and their benefits, discusses safety and legal issues, then goes on to explain how to build a bike with a hub motor kit. Also covers repair, maintenance, and more advanced projects.
An e-bike conforming to these conditions is considered to be a pedelec in the EU and is legally classed as a bicycle. The EN15194 standard is valid across the whole of the EU and has also been adopted by some non-EU European nations and also some jurisdictions outside of Europe (such as the state of Victoria in Australia).
Unlike drivers of electric cars who are plagued by “range anxiety,” electric bike owners don’t have to worry about running out of electricity: They can travel under their own power, assuming they’ve got the energy to pedal a bike that weighs 45 to 60 pounds. Batteries typically deliver 20 to 40 miles of assisted riding, and they can be recharged in a few hours in ordinary power outlets.
Pennsylvania is one of the states where non-ebikers who shouldn’t get involved are anyway. Let me explain why they look foolish for trying to control what they don’t even understand. PA vehicle code states 5 “requirements” or criterion which are critical to legal ebikes. the 3rd states in order for it to be a motor vehicle (not a bike) it MUST have an automatic transmission. Even though the code had the term “electric bike” added to it, it still left the “automatic transmission” requirement. Electric motors and bicycles don’t have automatic transmissions, and aren’t really classified in the vehicle code for that reason. Yet on Penndot’s (PA’s DMV) website there is a promiscuous “FACT SHEET” which says electric bikes are all illegal without registration and a DL. I would tell them to stop being so dumb, but I’ve noticed this approach rarely changes the ‘facts’, and I”ll just leave that nest of bees alone. I wonder who wrote that turd. Not one of us, we don’t step on our own rights, do we? I don’t even try to step on others’. But have to be careful where you step. I like laws. But they have to make sense. Ebikes are harmless and can reduce the plague of pollution to heal what I’ve seen become noticeably dirtier (waterways, snow) in my own lifespan, What a shame to even consider it being illegal.
Thanks for helping a little Southern California startup become a global company. A company that can not just hang with the big boys, but lead the way. Thanks for helping us stay true to our roots. For embracing innovation. For realizing that style and substance aren’t mutually exclusive.
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle. Schnepf’s invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection – our Direct-Drive motors are now all High-Torque 6×9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the…
As a power electronics engineer I had intended designing and developing a torque assist bike so was surprised to find that a few manufacturers brought them out in Europe recently. I bought a Raleigh Vélo Cité with a 36V 10Ahr lithium battery. I would never use a throttle or cadence type unless I was infirm and I am sure that torque sensing pedelecs will become the norm as prices fall.
As is always is the case with companies that launch products on Indiegogo, there’s a chance those things never happen. But if you’re in love with the idea and don’t particularly want to roll the dice on a startup, there are plenty of similarly priced portable batteries and solar panels already available on the market, and an abundance of e-bikes at or under Kvaern’s price tag. You might have to do a little comparison shopping if you want to find something that matches the Copenhagen startup’s style, but you’ll certainly be able to ride the sun’s rays a lot sooner.
Genze e-bikes offer a convenient “walk-mode” for maneuvering up stairs and steep inclines. When activated, your e-bike will move at a slow and steady pace, keeping you sweat-free. Stairs have never felt so flat.
I am a fan of as little components as possible. The less parts and pieces, the less chance of failure. That’s just my opinion. I do not offer pedal sensor components on my DIY kits but I am open to learning what people think / want.
Do you love vintage motorcycles? Then we have the e-bike for you! The Italjet Ascot is a gorgeously classy model, with retro-chic styling that includes leather handlebar tape, a built-in storage bag, and brown bubble tires. Still not enough glamour for you? A gold chain completes the package. Naturally, it has a leather Brooks Flyer saddle, too. Even the lights look vintage, but nothing about how this bike handles makes it feel old. It can get up to 15 miles per hour with the help of the battery—the rest is all your leg power. If you always wanted a Vespa but couldn’t justify a full-blown scooter, this is one step cooler.
If you live in an apartment or small house that’s short on space, consider the Kalkhoff, which is one of the lightest and most compact e-bikes on the market, thanks to folding pedals and swiveling handlebars. That makes it easy to store it flush with the wall in a hallway or on the train, and an internally-geared eight-speed hub makes it cleaner than your average bike. It’s also easily adjustable and one-size-fits-all thanks to handlebars and an extra long seat post that both adjust in a snap. It comes with a two-year warranty, which helps justify the expense of a new bike. Motor speeds top out at 20 miles per hour, and it lasts for a long time—up to 85 miles! At 50 pounds, it’s one of the lightest models available; making it more reasonable to pedal on its own if the battery wears out mid-ride.
I have put over 200 miles on my EVELO in the past few weeks. Nothing but fun. And more fun! After 25 miles on pedal assist I still have over half a battery charge left. Hills become flat. I have been riding on pavement, dirt roads, and trails in the forest. Riding a regular bike is quite a bit of work in hilly areas like where I live. My EVELO makes riding fun.
Yamaha will begin selling four models of its Power Assist Bicycles, including this YDX-TORC bike, described by the company as an “agile mountain bike with aggressive performance.” (Yamaha Power Assist Bicycles)

I bought an OutlawSS which tops out at 28mph. I tried the “discreet” route as stated above but because of the blood-red color and design of the bike I attracted too much attention. It didn’t matter that I was keeping my (alongside of the road) speed at 15mph, people (probably cycling enthusiasts or just haters) jammed on the brakes to check out wtf I was riding. One passenger (some teenager) even had his smartphone out and was either snapping pictures or getting video. Long story short, the officer that pulled me over said “no” to the bike and advised me to get an off-road sticker from the DNR and I’d be fine on ATV trails. He also said there have been numerous reports of “The guy on the illegal E-bike”. I was polite and got off with a warning. Haters gonna hate I guess.
Batteries: Battery packs can be fitted in all kinds of different positions, but often, they are fixed to a rack behind the rider. If you plan on carrying anything, this configuration could be problematic.

High pedal assist = you feel like superman! High pedal assist is when you want to get somewhere quickly and with minimal effort. This could be useful if you want to get to work without sweating too much. On the way home you could use the low pedal assist to workout the stress of the day.
The GenZe Companion app looks for active faults your 200 series e-Bike has submitted. If something is wrong, it will display the fault, and provide you with an appropriate action to resolve the issue.
This lightweight geared hub motor has a 5:1 gear reduction for increased torque. The freewheeling clutch allows the wheel to spin freely when the motor is not powered. The motor is set up with a high-end 9 Speed Shimano Cassette rather than the budget 7 speed freewheel systems. This insures more crisp gear shifts and even compatibility with 10 Speed setups
