The Espin is powered by a 350-watt motor that’s rated for trips up to 50 miles (depending on the terrain and assist level). Once depleted, the battery fully charges in roughly five hours. Thankfully, Espin makes it easy to remove the battery, allowing you to quickly recharge it at home or in the office between trips. A backlit LCD control hub displays your basic metrics and battery life while in transit and LED headlights add a touch of light when needed.
I know that this topic is new and still contentious, but the community needs to be talking about it because it isn’t going away. The weather up here in Seattle is rainy and cold (no surprise there), so I haven’t ridden my new eBike except around the block to make sure it worked. I can’t wait to hit the trails (legally or illegally). Expect a follow up comparing the eMTB to my other mountain bikes both in how it performs and the feeling I get from riding it. I never thought I would be riding an eMTB, so trust me, I won’t hold back.
It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:

Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It's worth looking at the quality of the brakes and investing in bikes with better ones if you can.
A stealthy, long travel, all-mountain electric bike with longer wheel base and adjustable seat stay hardware to optimize geometry for climbing and descending, proprietary "Active Braking Pivot" rear suspension reduces skipping, Knock Block headset and Hartzell Hug impact-absorbing downtube bumpers allow for straight downtube. Trek-invented Boost hub spacing improves spoke bracing angle and support for larger plus sized tires,…...
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.
If you haven’t ridden or even seen a modern eMTB, here is what I have discovered. They are sturdy rigs that come standard with quality mountain bike components including beefy forks and rear suspension systems, strong disk brakes, and a reliable drivetrain. They are heavy but not that far out of the old downhill bike weight class. The distinguishing “e” features are the electric motor at the bottom bracket (some have hub motors), the battery pack, and the handlebar-mounted computer that controls the system. They have adjustable assist modes: off, low (barely helps), medium, and the battery-draining high mode. When everything is put together, they are something to behold.

It means you can fit much more riding into one session. Or if you want to cover more distance (as often the best riding spots are quite far apart here in the UK) e mountain bikes are perfect for the job. All the usual MTB configurations are available – everything from wheel size to forks and more, and there’s the choice of hardtail or full suspension electric mountain bike too.
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.

Direct-to-consumer Italian brand Thok’s MIG bike has reviewers falling at its feet. Why? It simply offers a superb package – its geometry and construction are as on-the-ball as its choice of Shimano motor, battery placement – giving low centre of gravity – and quality build kit. At under £4k, the MIG is great value too (there is also a pricier MIG R, featuring upgraded components). Thok knows its stuff, which is hardly surprising when you look at its founder. Former champion downhill racer Stefano Migliorini understands what makes a good bike, and he personally leads the charge on bike development at Thok.

E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
A carbon frame shaves off several hundred grams of weight, of course. However, this is largely irrelevant when it comes to eMTBing. The two major advantages of carbon on eMTBs are, on the one hand, greater freedom in optimising the frame design and, on the other hand, increased stiffness. Thanks to carbon, smooth transitions can be achieved, better facilitating the integration of motor and battery. Unfortunately, the magical black material also has a few potential disadvantages. Carbon has poorer thermal conductivity, which means that heat is dissipated less efficiently with a fully integrated motor, and stiffer is not necessarily always better. Frames and wheels require a certain amount of flex to be comfortable and to generate enough traction through curves. Buying a carbon eMTB can currently only be justified by aesthetics rather than functionality.

Riding position: You also may wish to check out an e-bike’s riding position before investing in it. For short trips, the riding position might not make much difference, but for long journeys, the upright "Dutch" style with pulled-back handlebars is very comfortable – particularly for tall riders. The same goes for mountain bike styles, though these bikes are not often designed to actually go off-road.
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 years of experience have clearly shown that it isn’t possible to make a universal and realistic estimate of an ebike’s range. The range of an eMTB depends on countless factors such as the support level, terrain, rider weight, environmental conditions, and cadence. Those who demand a lot of power from the motor consume a lot of electricity. If you want to travel far, you’ll have to save battery power. Read more about this topic in our article The truth about lab tests.

“People are buying electric bicycles as a way to reduce car trips,” Benjamin says. The data backs him up: 28 percent of survey respondents said they bought an e-bike specifically to replace driving a car. And many other reasons buyers listed for wanting an e-bike—including carrying cargo and kids, avoiding parking and traffic, and environmental concerns—also indicate a desire to get out from behind the wheel. Plus, you don’t need to change clothes or clean up when you arrive at your destination, because you don’t have to work up as much of a sweat.

Like the Bolt, the GM bikes are very much urban-oriented, which as the ongoing CleanTechnica series shows is a strong sweet spot for electric two-wheelers. One thing that leaps out of its contest page is part of its vision for the bike: “Zero crashes.” As a recent CleanTechnica article pointed out, there have been a growing number of injuries and some fatalities associated with electric bikes globally. What GM means by ‘zero crashes’ is unknown, but perhaps it’s more than just an interesting throwaway line in marketing.
When did mountain biking get so uptight? As we see it, fun is a right, and no matter where or when you're riding, it should always be at the heart of each pedal stroke. So whether you're on singletrack, sand, or snow, the Fatboy will deliver a good time. It has tire clearance for up to five inches, a lightweight M4 aluminum frame, snappy handling, and rack mounts that make it adventure-ready, the question is, 'what's taken you so long?'
Introducing a fully integrated, electric-assist mountain bike that takes our Altitude’s legendary handling and ride quality and adds a compact, powerful drive system. The new Powerplay™ drive system was designed in parallel with the frame, delivering ultra-short chainstays, optimised suspension kinematics, super-low centre of gravity, and class-leading torque. The result is an e-MTB that actually rides like a proper mountain bike—perfect for everything from self-shuttling all mountain trails, finding flow between the descents, and squeezing in power lunch rides. 

The downhill performance is our most highly weighted rating metric because we feel that the most important element of an e-bike is how well it performs out on the trail, especially when bombing down the hill. Each tester rode every bike numerous times and formulated their own opinions of each model, considering how factors like the component spec, geometry, and frame design play a role in its downhill performance. All of the e-bikes we tested were fun to ride, way more fun than any of our non e-bike riding test team ever expected, but they all had a different demeanor and trail manners. To test this, we rode the bikes downhill, a lot, and took them down a variety of terrain, from fast and flowing open trails to tight low-speed technical, and everything in between.
The Haibike AllMtn line makes an appearance again with this incredible price-point option. The AllMtn 6.0 is a nice option with entry level components but the same aggressive build as the rest of the AllMtn line. And when I say entry level components, I definitely don’t mean that as a negative. You still get 150mm of travel with a Suntour Aion 35 RC suspension fork, a RockShox Deluxe RT rear shock, Magura MT32 hydraulic disc brakes, and Shimano Deore M6000 drivetrain with 20-speeds.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
