Government agencies like the USDA National Forests and the Bureau of Land Management should distinguish between electric pedal-assist eBikes (Type 1) and self-propelled eBikes (Type 2). The former are still human-powered whereas the latter are fully motorized like a motorcycle. Some states like California are already recognizing the different classifications of eBikes and allowing some on trails while prohibiting others. This clear distinction should help us avoid expanding our mountain bike trails to motorcycles, or worse yet, have trails that are currently open to mountain bikes relegated to “hiking only.”
Electric Bike Conversion Kits are prepackaged sets of components designed to fit on a normal bike and convert it into an Electric Bike. These kits make it easier for end-users to find compatible, functioning parts and purchase them all together. A kit can range from a complete system that includes all the small parts you need, to DIY kits that include only a few parts and leave the rest up to the user.
E-bikes are zero-emissions vehicles, as they emit no combustion by-products. However, the environmental effects of electricity generation and power distribution and of manufacturing and disposing of (limited life) high storage density batteries must be taken into account. Even with these issues considered, e-bikes are claimed to have a significantly lower environmental impact than conventional automobiles, and are generally seen as environmentally desirable in an urban environment.[65]
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.
For those who aren’t frequent riders, e-bikes open up a whole new world. While you may not be conditioned to ride 5-10 miles at a time, you can cover those distances easily with an electrical assist, which is a great way to build endurance and confidence. That same survey found that 94 percent of non-cyclists rode daily or weekly after getting an e-bike.
Generally speaking, e-bikes are bicycles with a battery-powered “assist” that comes via pedaling or, in some cases, a throttle. When you push the pedals on a pedal-assist e-bike, a small motor engages and gives you a boost, so you can zip up hills and cruise over tough terrain without gassing yourself. Called “pedalecs,” they feel just like conventional bikes—but better, says Ed Benjamin, senior managing director at the consulting firm eCycleElectric. “You control your speed with your feet, like with a regular bike,” he says. “You just feel really powerful and accelerate easily.”

Since joining E-BikeKit in early 2010 Glenn has had a huge impact on the success of the company...
E-bikes can be a useful part of cardiac rehabilitation programmes, since health professionals will often recommend a stationary bike be used in the early stages of these. Exercise-based cardiac rehabilitation programmes can reduce deaths in people with coronary heart disease by around 27%;[55] and a patient may feel safer progressing from stationary bikes to e-bikes.[56] They require less cardiac exertion for those who have experienced heart problems.[57]

Most consumers want an e-bike that will accommodate its motor without being too cumbersome and will remain stable in spite of its electronic components. Some consumers want only the most basic of e-bike features, including lights, a cargo rack/basket, and a water bottle holder. Others are focused more heavily on safety features, such as brake type. And still others are concerned with convenience and portability.
The final appearance of both the FullSeven and the Yamaha PW-X on the countdown. This top notch 27.5″ wheeled shred sled is another perfect fire road rider for the intermediate rider looking to step their game up. One thing I didn’t mention before but I wanted to let you all know is that I think the FullSeven geometry this year allows the bikes to be more accessible to riders of all sizes. Traditionally, most companies offer one or two options for female riders. Haibike does offer the FullLife models, but the FullSeven series by and large offers better components and a very similar geometry. I think that’s great.
The demands for the best eMTB are high. It has to climb efficiently, be comfortable to ride, be very stable and composed, yet, on top of that, be a lot of fun on the descents. Also, its integration, ease of use, and motor performance must set the benchmark. Although all the motors perform at a high level, the Bosch Performance CX is unable to keep up with the competition due to the high internal resistance it generates at over 25 km/h. It’s a pity for the Moustache Samedi Race 11: it’s by far the best Bosch bike we’ve ever ridden, but it’s slowed down by the motor. With a price tag of € 5,999, the Trek Powerfly 9 LT Plus is clearly the cheapest bike in this group test. It climbs very efficiently, but is held back on the downhills by a poor choice of tyres and slow handling – you should consider a tyre upgrade in your budget. The Haibike XDURO Nduro descends with the stability of a freight train, but it has to let the competition overtake it when going back up. With its long 180 mm travel and high weight (24.54 kg), it even feels cumbersome on the downhills.
The Liv Amiti-E+2 is a low-priced but highly versatile e-bike. It’s just as much at home on the pavement as it is on bike paths and rail trails. But don't feel constrained to groomed paths. Front suspension and 42mm-wide tires mean you can take on off-road detour on your way home from work. Speaking of work, this e-bike makes a great commuter thanks to rack and fender mounts and integrated lights for riding after dark. Internal cable routing and a nicely integrated battery make for clean lines and 9-speed shifters give you plenty of gearing options for whichever type of terrain you decide to tackle. This do-everything bike is great option if you’re riding includes a little bit of this and a little bit of that.
Having a motor bolted to the bottom of a mountain bike that provides pedal assistance is an amazing leveller. The constant torque it applies to the chain rounds out the squarest of pedalling actions, which in turn helps stabilizes the rear suspension and counter pedal induced bob, seamlessly shifting your focus from pedalling efficiency to battery life.
This is a question the designers and engineers of the FOCUS and BULLS bikes of this group test asked themselves. Instead of speccing them with the standard 500 Wh batteries, both have developed a sophisticated alternative. The idea: instead of riding around with unnecessarily large batteries and unnecessary weight on short tours, they integrated a smaller 375 Wh or 378 Wh battery into the bike. If you don’t have enough power for long loops, you can double the range of both bikes with an additional battery for up to a full 750 Wh. While the second battery is mounted in the front triangle of the FOCUS, it disappears sideways in the downtube of the BULLS. In practice, you’ll need the second battery relatively often with both bikes, and in either case, you should consider the additional € 499 investment in a second battery pack when you buy the bike.
Power delivery is smooth and easy to predict, once you get the hang of it. We’re not sure if integration is better on the Turbo road bike, or if the slow, technical nature of trail riding just highlights some quirks. The motor shuts off less than a second after you stop pedaling, and the onset of power delivery is momentarily delayed once you begin pedaling. And this did mean we had to adapt our riding style a little bit to deal with that slight lag. 
We’ve got to give you a Haibike downhill option considering their excellent history with downhill and enduro models. Downhill models are traditionally incredibly expensive, but the DwnHll 9.0 offers a slightly lower price point for a top mountain bike. The build is incredibly slack so you can rip downhill in ideal positioning. The PW-X motor makes climbing much more enjoyable as well.

With almost as many awards as technical features, it’s no secret why we opted to include HaiBike’s SDURO HardNice 4.0 in the list. First and foremost, this sleek aerodynamic ride doesn’t even initially come off as an electric mountain bike. That is until you experience first-hand the integrated Yamaha PW Drive Unit offering dynamic support and a top speed of 20 mph. Also, the bike features a shock-resistant skid plate that works to protect the motor from harm, and a Yamaha LED display that’s small yet robust and works to keep you informed on the bike’s status and functionality.
A good hardtail can be your answer to both the perfect trail bike and the perfect on-road bike. Their lighter weight also means a faster ride off-road. Haibike offers a full range of 27.5 and 29er wheel size bikes for trails and cross riding. The XDURO and SDURO lines mean a selection of drive systems and a range of power that only Haibike offers. 

Electric mountain bikes (eMTBs) are relatively new on the scene and mountain bikers are freaking out. “They shouldn’t be allowed on our trails.” “They are going to ruin the sport.” It reminds me of when the first mountain bikes started popping up on trails and hikers were panicking with visions of crazed bikers running them over. Well, their fears never materialized and mountain bikes have become popular tools for exploring the outdoors responsibly.
The Netherlands has a fleet of 18 million bicycles.[77] E-bikes have reached a market share of 10% by 2009, as e-bikes sales quadrupled from 40,000 units to 153,000 between 2006 and 2009,[78] and the electric-powered models represented 25% of the total bicycle sales revenue in that year.[77] By early 2010 one in every eight bicycles sold in the country is electric-powered despite the fact that on average an e-bike is three times more expensive than a regular bicycle.[73][78]

In 2012, two e-bike advocates completed the first 4,000-mile (6,400 km) transcontinental e-bike tour from New York to San Francisco to advocate for e-bikes in major cities across the U.S.[81] Pedego Electric Bikes is the best selling brand in the U.S. Many e-bikes in the United States are standard bicycles converted using a kit. In general, the kits include the motor (the majority of which are hub motors built into the front or rear wheel), a speed controller, throttle (usually twist-grip or thumb throttle), necessary wiring and connectors, and a battery. Several U.S. companies offer conversion kits which also offer advanced lithium battery packs. Major manufacturers also offer complete e-bikes. Trek offers a line of e-bikes using the Bionx system in which the rider programs the controller to determine how much effort the motor will give in response to rider effort, from 25% up to 200% of the rider's power. This system ensures a minimum level of rider participation and is also used to comply with many European laws mandating partial human effort before the motor engages.
Countless others have popped up since all over the world, proving that the design has been popular with consumers. However, most people don’t know where the craze started. In fact, it can all be traced back right here to Coast Cycle’s original Buzzraw, which actually started life as Coast Cycles’ Ruckus bike. The Singapore-based company quickly changed the name to Buzzraw, probably fearing Honda’s lawyers.

Built by a company that’s made cycling equipment for more than four decades, the Vado feels more like a traditional bicycle than almost any other ebike. Its frame and components have been tuned to provide a familiar experience, making it easy for new and long-time cyclists to jump on and start pedaling. Specialized’s heritage shines through nicely, helping separate itself from the competition in an increasingly crowded ebike market.
When looking for the perfect ebike, there are a lot of things to consider. There’s price, weight, capabilities, performance and something that’s hard to quantify: feel. That’s a combination of factors that is affected by the geometry of the bike, its materials, components and other nuances. I took a ride on the crowd-funded Carbo folding bike this week and I’m not sure I’ve ever felt as comfortable on a folding bike in the city as I did on this extremely light, yet powerful ebike.
The new Stumpjumper is the ultimate trail bike. Seriously, the damn thing rides like it’s on rails. It’s the most versatile trail bike we’ve ever made. And yeah, we’re stoked about that, but we’re even more excited about how well it’s tuned to you. We’ve said goodbye to proprietary bullshit, focused on your needs, and made, what we feel, is the new benchmark in trail bikes.

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...

Looking for electric mountain bikes? Propel has you covered. We carry many different types, most of which have a center drive motor since they perform best on the trail and they’re great for climbing. Our bikes have motor systems from leading manufacturers including, Bosch, Shimano, Brose and Yamaha. Most electric mountain bikes or EMTB’s are limited to 20 mph, but some do go up to 28 mph. We carry many different types listed by category below. We have full suspension, hardtail, fat tire, carbon fiber eMTB.
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.
There’s a feeling people get when everything just clicks on a ride, and the Roll is a bike that pulls it all together for you. Take it on a bike path and enjoy the smooth ride afforded by a lightweight frame and Ground Control Positioning. Feel the confidence a wider, more stable tire provides. And ride longer with the Body Geometry science that’s gone into the saddles, grips, and pedals. Get out there, get active, and feel it for yourself.

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.
Tackle your daily commute with ease or go for a weekend cruise in style with the Gazelle CityZen T10 e-bike. And don’t worry about those thigh-burning hills; the Bosch motor offers four assist levels—Eco, Tour, Range Sport, Turbo—making hills a breeze and the Lithium-Ion battery provides a range of up to 85 miles in Eco mode. The bike is one of the first to use Bosch's new integrated battery, which is concealed in the downtube. The matte black paint and classic, step-through design give a classic look while fenders, pannier racks, and integrated lights add practical functionality. The bike is easy to maneuver in city streets, but still has assist up to 28mph so you can cover a lot of miles and power up steep hills. There's a suspension fork too. It's not at the level of something you'd find on a mountain bike (or even some better e-bikes) but it takes the edge of some potholes and curbs.

Powered by a 250-watt Brose Centerdrive system, the Redux is capable of reaching speeds of up to 28 mph, which comes in handy when dodging traffic. Its 36-volt lithium-ion battery provides enough juice to give the bike a range of up to 80 miles between recharges, making it a great option for daily commuters. Raleigh even outfitted the bike with wide tires which provide stability and traction, even when the road gets wet. Other key features include a 10-speed Shimano crankset and shifters and a built-in LCD screen that displays all the usual information.
Name a type of riding, and there’s an e-bike for that. If you have zero interest in an electric road bike, you may find yourself head over heels for a high-capacity e-cargo bike that can haul 400 pounds of stuff while still cruising at a cool 15 mph. E-bikes are available in fat, cargo, commuter, recreational, hardtail, full-suspension mountain, and even performance road bike styles. For proof, here are a dozen e-bikes we love for every type of cyclist.
Your friends: We all have friends we wish wanted to pedal up hills with us. Many of who might be capable of leaving us in their dust on descents. These are young and old riders; riders lacking the fitness, time, motivation, or who just aren’t interested in climbing alone, at the back of the pack. You’ve done everything to get them back out riding with your regular crew, but pride and reluctance to hold the group back is keeping them away. 

Introducing the future of performance and comfort, the Kinekt BodyFloat seatpost. The innovation isolation system, designed here in Washington, greatly enhances the endurance and enjoyment of riding a bike. Engineered to be infinitely tunable to fit your personal riding style and weight, Seattle Electric Bike is proud to offer this breakthrough seatpost for all your biking adventures.
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.
Consider, too, that more than half of all driving trips are shorter than 10 miles, with some surveys reporting that the average single trip amounts to just 5.95 miles. That’s a no-brainer distance to cover by e-bike. In fact, the survey found that owners replaced 46 percent of their car commutes and 30 percent of their driving errands with e-bike rides. All you need is a great commuter bag to carry your stuff, and you’re set.

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.

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.
