In the geared motor, a small and lightweight motor spins very fast inside. The electric bike motor then uses a planetary reduction gear inside the motor to reduce the rpm to the correct speed for a bike wheel. Electric Bike Motor An electric bike motor on an electric bike can be any kind of electric motor. There have been some very creative home brew e bikes that used any motor...

The box looked rough. Lots of little digs and dents. When I opened the box, the contents were very well packed. Mine did show that it took a good hit to the headset stem as the spacers where shoved and the clear tape was all bunched up and the one spacer was almost at the edge. After taking the tape off, cleaning all the tape residue off everything went together super easy. I used the included multi tool to do most of the assembly. I just needed a wrench for the peddles.
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””
No day or ride is the same. Monday could be morning park laps, while Saturday might mean a day in the woods. If this is familiar, you need a bike like the CrossTrail. It has a responsive, durable aluminum frame, while our Body Geometry Fit science and a Multi-Circuit Damping fork ensure comfort over any terrain. Put it all together, and you have a bike that's just as versatile as yourself.
Direct-sales German brand Canyon’s entry into the e-MTB market came with a bang. The Spectral:ON is a stunning bike with a superb build kit, decent geometry and respectable weight (21.2KG listed weight). As with anything Canyon, it’s hard to find better value for money. The entry-level 6.0 is down there with the lowest-cost serious e-MTBs available, yet its build kit, including RockShox Yari fork, Schwalbe Magic Mary tyres and Shimano Deore XT derailleur, ensures the bike punches well above its price.

Wide tyres are an absolute must on an eMTB. They offer more traction, provide extra comfort, increase stability, and they simply look cooler. Tyres with a width of 2.5″ – 2.8″ have proven to be the ideal size. The performance of the MAXXIS Minion tyres is particularly impressive; they provide the best grip and stability. To get the best performance, tyres should be ridden at approx. 1.2 – 1.6 bar air pressure.
On mine I got the Topeak front and SKS rear mud guards, an Axiom rear rack, front and rear lights. They didn’t have a headlamp with the lumens I wanted, so Tommy the owner went ahead and ordered one for me! He was always available for any question I may have had through his mobile phone, and updated me with pictures showing me different possible setups to see if I would like it.
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.
For those who know the brand, Ducati makes lust-inspiring road motorcycles, covering the range from scramblers to naked bikes to sport bikes. They’ve topped podiums globally, appeared in too many movies to name, and in some cases have ended on display in art galleries. But like everyone in the motorcycle business, the company is challenged by global changes and is looking to capitalize on its valuable brand. Likely it was challenged to by its corporate overlords, as the Ducati company was acquired by Audi and hence VW in 2012.
Home is the one place you can feel comfortable in your own skin. You can be yourself, invite people in, or close the door to the world. To be 'at home' on the Ruby is to shut out the negative, to truly relax into who you are. If that's someone who's into the harshest of roads? Relish in them. Or if you want the smoothest ride in the world? Welcome home.

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-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[58] 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.[59] Reaching VO2 Max, can really help your body as a whole[60]. 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.[61]
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.
As my boys were growing up in the 2000s, we would bike together in local parks and I always dreamed of taking them on my favorite big rides when they reached their teenage years. But in 2012 I started getting sick and I didn’t know why. Two years later, after countless doctors visits, tests, and head scratching, I received some bad news from my doctor: somewhere in my adventures, I had contracted Lyme Disease. My life has never been the same.
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.
The removable 460 Wh battery is hidden in the downtube, and the custom-built-for-Specialized Brose motor is integrated around the bottom bracket, and develops 250 watts of power. A torque sensor detects when you’re applying pressure to the pedals, and provides assistance when you need it. Aside from the glowing green LEDs indicating charge levels and output settings, there is little indicating this Turbo is anything but a typical mountain bike. 

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.
Basically, there is no reason to ride an eMTB with less than 130 mm of travel. With classic bikes, more travel usually means both less efficiency and poorer climbing characteristics, but this is not true with eMTBs – at least not up to a certain point. The best example is the Specialized Turbo Levo, which with its 135 mm of travel at the rear handles much better than most of the other, longer travel bikes in the group test. Also, eMTBs with suspension travel of 180 mm or more are often noticeably less efficient, as clearly exemplified in this test by the Haibike XDURO Nduro. It climbs a lot slower than other bikes using the same motor and the same level of assistance, an experience you will find with almost all other long-travel bikes from other manufacturers. The exception is the BULLS E-CORE EVO EN Di2: in direct comparison, it climbs a lot more efficiently, even though it also offers 180 mm of travel. The ideal compromise between uphill and downhill performance usually lies somewhere between 130 and 160 mm of travel.
With its steep seat tube angle and powerful motor, the Rotwild E+ Ultra masters even the steepest climbs. Its high centre of gravity, however, negatively effects downhill handling. The GIANT FULL E+ 0 is a very solid eMTB where what you see is what you get, although the rather slack seat tube and bulbous-belly isn’t exactly pretty. Not so with the FOCUS SAM²: With its clean silhouette it is a bike for design lovers. But only if you get by with the small integrated battery. As soon as you mount an additional battery, not only the appearance suffers, but also the handling. The BMC Trailfox AMP has minor weaknesses in the componentry, finish and downhill handling – at a price of € 12,000 we expected considerably more. The Thömus Lightrider E1 fares better, it’s no bargain either, but the handling is outstanding. It’s a pity that the bike isn’t available outside of Switzerland. Another exotic specimen is the FANTIC XF1 Integra Enduro 160. The bike from the Italian motorcycle brand can’t deny its roots, tremendously composed and capable on the descents, though it cannot keep up with the competition when going back up – the 180 mm version of the Fantic is significantly better overall.
For Canyon’s first e-mtb the Spectal:ON 8.0 hasn’t simply hit the trail running, it’s power up it in Boost mode. The geometry, sizing and handling are all on point, and details like the adjustable geometry, odd wheel sizes, tyre specific rim widths and short cranks make Canyon a market leader rather than a brand that’s simply playing catch up. With a Fox 36 Fit4 fork the Spectral:ON 8.0 would probably have won the test, the more basic Grip damper never having the measure of Canyon’s superb rear suspension.

The need to develop a high-performance e mountain bike provoked the launch of the ATOM X project over three years ago. A team of experts was put together from the fields of MTB geometry, suspension and performance, advanced motor, battery and IT technologies. That is how the innovative and patented “X System” came about, which represented an integration that was both ergonomic and different. It was developed until it became the best eMTB with the best of both worlds: high performance and the most advanced electric technology. See the ATOM X e mountain bikes...

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.
Focus manage to offer both one of the lightest all-mountain capable e-MTBs and also one of the greatest battery ranges. How do they do it? Simple. A smaller-than-most, 378Wh battery is integrated into the frame (the other bikes in this list feature a battery around 500Wh). Another, optional, 378Wh battery also attaches externally within the mainframe. It’s a novel idea, and the bike is noticeably more playful than some others in its lightweight guise. 
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.[43]
