Automated Transit Networks (ATN), and the small-vehicle subset of Personal Rapid Transit (PRT), are emerging technologies that can help solve the related problems of congestion, dependence on foreign oil, and planetary climate disruption. ATN/PRT offers clean, quiet, responsive public transit with automated non-stop service available 24 hours a day. In addition to these service benefits, PRT costs far less to build and operate than other transit options ¯ and is safer than walking and cycling on nearby busy streets.
Whether you're riding in the backcountry or racing enduro, you need a bike that's capable and efficient. After all, to ride 'all mountain' necessitates riding the entire mountain. That's why our Enduro line of all mountain bikes, both in 650b and 29er options, come equipped with loads of travel, lightweight constructions, and geometries that can handle themselves on anything from downhill tracks to stomach-wrenching climbs.
Probably the only readily available, mass-production downhill-specific e-MTBs on the market… well, downhill preferred anyway. Don't be afraid to test the limits on this one! Haibike’s xDuro Downhill’s intention is to assist with the pedal back to the top so riders can self-shuttle, instead of taking chairlifts or vans to the top. If you are Haibike pro rider Sam Pilgrim, you could also use this bike to go upside down over enormous jumps. The e-DH bike is a good idea – who can argue that fewer shuttle buses needed to ferry gravity fiends is a bad thing?

Electric bikes and E-bike kits (bikes with electric conversion kits) are part of a wide range of Light Electric Vehicles (LEVs) that provide convenient local transportation. Generally designed for one person and small cargo capacity, electric bike range, speed, and cost are moderate. For most of us, the majority of our trips are less than 20 miles - within the range of most e-bikes considering the latest advances in affordable lithium batteries. Clean, quiet, and efficient LEVs offer the advantages of an extra car without the burdens.
Bosch’s flagship mountain bike system uses a mini drive ring with internal gearing to send its power to the drivetrain. There’s some resistance in the system over 25km/h, but when you first press down on the pedals there’s an impressive surge of power, and it offers good support over a wide cadence range. Its size has an impact on the width of the cranks (the Q-factor) as well as the chainstay length of the frame, and it’s not the lightest system on the market at 4kg for the motor. On the other hand, Bosch is the most established player on the market, and its system has proven itself over many years.
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.
In the year 1885, a British man named J.K. Stanley introduced what can fairly be described as the first modern bicycle. His Rover bike had wheels of equal size in the front and back and used a chain connecting the pedals and the rear wheel as a propulsion system. It was often marketed as a safety bike in contrast with the unstable Penny Farthing, and was a smashing success. The company went on to develop motorcycles and automobiles, remaining in business until the year 2005.
There's no room for failure in DH. That's why our Demo 8 downhill mountain bikes get right down to business. They're designed to be the fastest bikes on the track, and with a World Cup overall, it's safe to say that we did it right. You'll find 200mm of our FSR suspension, aggressive S3 DH race geometry, asymmetrical frames, and 650b wheels. It's a machine primed to give you maximum control over the gnarliest terrain that the mountain can muster.
If exploration is the new black, then the Ariel is a bike dressed for adventure. Versatile and reliable, hit the road with purpose as you chase down your fitness goals, then satisfy your inner explorer as you veer onto the dirt with confidence. Its Women’s Custom tuned suspension and Multi-Circuit Damping fork turn rough to smooth, while giving you more control as you explore your world on two wheels.
If you’re looking for even more performance and an even more refined bike, you’ll find what you’re looking for at Specialized. Their bike embodies the company slogan “Innovate or die” in a perfect way and is full of smart solutions. Many of them, such as the specially developed app for tuning the motor, the integration of the battery, and the small remote lever for selecting the support level, are obvious. Some, on the other hand, only become clear when you take a closer look – such as the Autosag valve on the shock for a simplified setup process, or the omission of a spoke magnet. The Levo also won us over with its outstanding riding characteristics, obviously. It rides comfortably, climbs quickly and efficiently, and has exactly the right mix of agility and stability. It’s the ultimate machine that promises to bring a huge smile to every rider’s face after just a few metres on board – no matter whether beginner or a pro. The Specialized Turbo Levo S-Works Carbon is currently the eMTB offering the best overall package, and thus the deserved Best in Test! The best eMTB of the 2018 season!
Many many thanks for your wonderful customer services, and a wonderful bike you had prepared for me. Now, this bike becomes my physical therapy machine and a commuting transportation in the busy streets of San Francisco. Truly, the R15 upgrade is a very powerful e-bike. I can practically say that this bike is a hybrid of motorcycle and bicycle. The… Read more ““Just no comparison””
Stop and go with care. Because you’re heavier and faster, it will take longer to slow down and stop. Squeeze your brakes well ahead of intersections. Remember that the bike will accelerate faster than normal, so don’t start pulling out into traffic until it’s fully clear. Also, because the bike has some heft, you may feel wobbly the first few times you get going or slow to a stop. Practice mounting, dismounting, and stopping in safe places before hitting heavily trafficked roads.
You've gotta get up to get down and one of the purposes of e-bikes is to make it much easier to do so. Since we spend significantly more time climbing than descending, we felt it was important to rate how well these bikes perform when pointed uphill. Climbing on an e-MTB with pedal assist support is somewhat different than climbing on a bike without a motor. These bikes are capable of carrying some serious speed uphill, changing the climbing dynamic with a much faster pace, often tossing finesse out the window in favor of power and momentum. The heavy weight of these bikes and plus-sized tires gives them incredible traction, keeping them planted on the ground, and dampening switches can be left wide open to enjoy the added traction benefits of active rear suspension. Each bike's geometry, handling, and power output all played a role in how well these bikes performed on the ascents, and we had plenty of time to test them while rallying back uphill for more downhill laps.

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, and reaching an estimated fleet of 120 million e-bikes in early 2010. 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. Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car. Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007. 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.
E-bikes can also provide a source of exercise for individuals who have trouble exercising for an extended time (due to injury or excessive weight, for example) as the bike can allow the rider to take short breaks from pedaling and also provide confidence to the rider that they'll be able to complete the selected path without becoming too fatigued or without having forced their knee joints too hard (people who need to use their knee joints without wearing them out unnecessarily may in some electric bikes adjust the level of motor assistance according to the terrain). A University of Tennessee study provides evidence that energy expenditure (EE) and oxygen consumption (VO2) for e-bikes are 24% lower than that for conventional bicycles, and 64% lower than for walking. Further, the study notes that the difference between e-bikes and bicycles are most pronounced on the uphill segments. Reaching VO2 Max, can really help your body as a whole. Professor Janet Lord of Birmingham University in the UK published a study that looked at older cyclists, ““The study looked at muscle mass, blood cholesterol, their VO2 Max, lung function, and in many of those measures we found they didn’t age! No loss of muscle, their bones were a little thin (but nothing like the general population), their blood pressure didn’t go up.
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.
For those looking for a fast, versatile, and highly capable full suspension ride should seriously consider taking the Powerfly 7 FS Plus for a spin. Reason being, not only does the ride host an integrated mountain-specific Bosch motor with a top speed of 20 mph, but a full RockShox suspension setup, mid-fat tires for enhanced stability, and high-end mountain bike components work to elevate your mountain biking experience for the better. From rough to nearly impenetrable terrain the Trek Powerfly could very well be the solution to your desired exploration.
Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.
