The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.[66]
My left crank arm came loose and seems to have damaged the square bottom bracket mount. I assumed the bottom bracket was just a standard square taper, but noticed it says “8fun” on it. However, I can’t seem to find an 8fun bottom bracket available online, so I can’t figure out what part I need—I suspect there is a something obvious that I’m missing. Any ideas to get me back on the road? Thanks all.
Hikers on Mt. Tam used to say we're crazy. Roadies called it a fad. Clunkers, tension discs— we left our eyes open, heads down, and kept designing. We kept evolving, and today, the Men's Turbo Levo FSR embodies a design unimaginable 40 years ago—a trail bike with pedal-assisted power on the climbs. A trail bike that gives you the power to ride more trails.
What does this mean for anyone with Stark Drive that was backed with greater then a 250W motor? Quite simply, it means that as long as you have not modified Stark Drive in any way, and depending on your local countries regulations (if they differe with this EU Standard) you are now able to use your bike legally in your location no matter where you are in the EU.

Yes, there are less expensive ebikes on the market but most come with a few serious caveats. The Espin Sport delivers on the full promise of an electric bike, but in a more affordable fashion. This bike isn’t going to tow you around for a 60-mile round-trip endeavor but those seeking their first ebike will get plenty of return on their investment with this model.
The Dew-E packs functionality and fun into a rather traditional and conservative package. Front and rear fenders, integrated Busch & Müller front and rear lights, and a built-in Abus wheel lock make this a very practical commuter bike. An 11-34t 9-speed cassette and 1.75-inch tires provide versatility: You’ll stay smooth over rough city streets and zip down gravel bike paths with confidence. Front and rear rack mounts also give you the chance to outfit this bike for carrying more cargo or supplies for a longer day on the bike. Whichever way you think you’ll be riding an e-bike, this bike deserves a second look.
But astute readers are surely wondering about the specs, as are we. Unfortunately, there is little to no information on it … making it a bit difficult to come up with a fitting name. But, seriously, the only thing we know so far is that it will have a USB charging port and LED lights, according to GM. The automaker bikemaker is keeping everything else secret. Perhaps as it simply hasn’t decided on the final specs. We’re waiting for company comments.
As a household name, Specialized is to be trusted in this world without a doubt. That’s because, in addition to their inventory of pedal-powered machinery, they’ve gone ahead and introduced us to their S-Works Turbo. Here, in conjunction with their custom Trail-tuned motor for off-road use, the Levo FSR frame is constructed entirely of FACT 11m carbon fiber allowing for both a lightweight and stiff ride through the local wilderness. Additional features include instant engagement, heat management, and a silent output for good measure. Not bad Specialized. Not bad at all.
E-bike usage worldwide has experienced rapid growth since 1998. In 2016 there were 210 million electric bikes worldwide used daily.[33] It is estimated that there were roughly 120 million e-bikes in China in early 2010, and sales are expanding rapidly in India, the United States of America, Germany, the Netherlands,[2] and Switzerland.[34] A total of 700,000 e-bikes were sold in Europe in 2010, up from 200,000 in 2007 and 500,000 units in 2009.[35]
The extra grip a 50lb e-bike normally helps to prevent overshooting corners when on the brakes, and bring pure DH-bike-like fun factor on the steepest trails. This electric Orange, however, rides more like a ‘standard’ enduro bike with a motor, which could be good or bad, depending on your expectations and riding style. It’s built tough and delivers stacks of fun in less time than any regular bike can. Adding a motor hasn’t upset Orange’s superb geometry.
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.

On the descents, the Commencal felt somewhat one-dimensional, great when up to speed, but with sluggish and less nimble handling hindering its performance in tighter, low-speed technical sections of trail. The Meta Power Race also had the shortest distance range in our head to head testing, another factor which kept this contender off the top step of the podium. That being said, this e-bike was built for charging, no pun intended, so if you're an aggressive rider who lives for eye-watering descents, then this might be the e-MTB for you. Read the full review to find out more about the Commencal Meta Power Race 650B+.

China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]

Last year, the Trek Powerfly 9 LT was one of the only ebikes with geometry and handling that came close to a modern enduro bike. For 2018, Trek has built on that winning formula with new frame. It’s lowered the battery in the downtube, while adding a stiffer Fox 36 fork, more powerful SRAM RE brakes and a stronger Bontrager wheelset. All welcome improvements to a really capable bike. The price has also crept up to reflect the changes. The biggest transformation however, is that Rocky Mountain has raised the ebike bar to a new high with the Altitude Powerplay.

After a couple years of strong antibiotics, a strict diet, and lots of rest, I was getting better so I thought I would try biking again. My son Andrew took me for a modest city ride and my Lyme symptoms spiked for three solid weeks – malaise, headaches, and weakness returned. I realized that I would probably never ride bikes again. After talking with my doctor and doing some research, I found that easy to moderate exercise can be beneficial, but strenuous activity can be detrimental. With mountain biking it is difficult to avoid exertion except with lift-assist or shuttles to trails with uninterrupted descents. Typical mountain bike rides with even slight hills like my city ride would probably send me into a tailspin again.
While I was waiting patiently for my 2017 model eBike to be manufactured and delivered, I came across an article in the local paper about a woman with a degenerative muscle disease who wants to take her eBike on forest service trails that are designated for mountain bikes. “What the hell?” I said, completely floored (what I actually said isn’t fit for publication). When I ordered this bike, the thought hadn’t even crossed my mind that it would be illegal to ride on mountain bike trails with my new, albeit electric, mountain bike.
Forward-thinking parents are giving up thier SUVs and opting for electric cargo bikes for getting the family around.

From toddler-friendly walk bikes to pint-sized helmets, we have everything you need to get your little ones away from the screen and out on their bikes.
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.
Enjoy the thrill of the ride without the struggle. Although it looks just like a normal mountain bike, as soon as you pedal you will feel the difference. The Gtech Mountain eBilke has an easy to read LCD display, to tell you exactly how much charge you’ve got remaining. Ride for up to 30 miles on a single charge. For adventurous riders tackling more challenging conditions, the range may be reduced to 10 miles per charge**.

Not the best bike but good for what it is. 250watt. not enough power even for small hills on its own and does not do 15/hr even on flat ground. battery looses power when cold but still works. Over all so far, dispite the above I give it 4 stars because it is what you would excpect in a cheap bike and it does work. There is no braket for the headlight tho so be warned you will have to improvise on that.
It’s important to note that because this is an electric bike, not all trails are legally accessible. You’ll need to check with the federal, state, or local land management agency in charge of the trails you want to ride to see if it’s possible. You may also face some resistance from holier-than-though cyclist types. Those guys are best avoided anyway, and the glowing LEDs on the down tube should at least help you identify them quicker. 
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.[36][37] Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes,[38] have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging.[39] 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.[40] 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[41] created 18650 battery packs[42] are commonly used among Do-it-yourself ebike makers.
