Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.

While this set off some excitement among Tesla watchers who also love two-wheelers, it’s much more likely that any e-bike that emerges will be a limited production run, Tesla-branded bike built with one of many great e-bike companies in California. Like the Tesla carbon-fiber surfboard or the Boring Company Flamethrower, it would provide excellent press, be offered at a high price point, sell instantly and be even more good marketing for Tesla. It might be a folder designed for the Model S frunk or other niches on the Model 3 or X. On the other hand, e-bikes are becoming a high-volume, global business and Tesla is well positioned with global retail space, excellent access to batteries, and big factories to get around for its staff. There might be a permanent product in place. Regardless, a dozen e-bike manufacturer CEOs undoubtedly picked up their smart phones and tried to get through to Musk or his execs immediately to offer their services.
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.

One of the biggest drawbacks to any ebike is its range — and perhaps to a larger extent, the capacity of its compatible battery. Since battery technology innovation is fairly stagnant, the German ebike company Riese and Muller decided that instead of making a bigger battery, it’d just slap a second one onto its latest release, the Delite nuvinci. Though the attachment does add more to the final price (to the tune of $823), it also increases the Delite nuvinci’s range to a whopping 130 miles — which is leaps and bounds further than any other ebike on this list.
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. 
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
The Best in Test and Best Value tips do not result from the sum of star ratings, but by the assessment of the entire test team, taking into account the overall concept of the bike. It would be methodologically wrong to only add up the star ratings to make a final judgment in a scoring system – saying that something is “good” will not help anyone if they don’t know what it is for and for whom it is “good.” For this reason, we give a clear recommendation in every test result for which type of rider and purpose the bike is suitable and which not. The bikes themselves are as individual as the riders are – we just want to provide you with all the information you need to make a well-informed decision before buying. Here’s to long-lasting fun!

When you are one of the top car manufacturers in the world witnessing an ever-changing landscape of reluctant buyers, what should you do? Ideally, you take scope of what works and phase out what doesn’t. GM’s bold Bolt plan was to offer the electric vehicle (EV) as a personal means of transportation and a shared mobility platform through its Maven program. We haven’t heard much from that initiative and it seems GM is ready to get in bed with the top two ride-hailing companies, Uber and Lyft. Is GM a bit lost in its strategy? Or is it figuring out what works and sharpening its vision?

When all was said and done, the Commencal Meta Power Race 650B+ proved to have everyone's favorite e-bike controls. Commencal uses the Shimano Steps E8000 motor and system which features ergonomic thumb shifters, a small but easy to read digital display and a secure and straightforward charging connection. The ergonomic shifter of the Shimano system is better than the electronic buttons found on both the Specialized, HaiBike and Trek. The Commencal's best-in-the-test digital display also proved to be a favorite for its small size and out of the way mounting location, easy to read at-a-glance information, and color-coded support settings information. The HaiBike's Yamaha PW-X motor and system also featured a digital display, but testers thought it was a little too big, displayed too much information, was more challenging to read, and generally felt a little more clunky and less refined than the Shimano system. That Trek Powerfly's Bosch Purion shifter and display unit was easy to read and had a bright screen, but was in a less visible location on the left side of the handlebar. Our Editor's Choice Award winner, the Specialized Turbo Levo FSR Comp 6Fattie scored the lowest in this rating due to the lack of a handlebar mounted display and a less user-friendly charging connection.
For the budding athlete, consider the gift of an electric bike, or e-bike, this holiday season. Whether your dad is a regular biker, or your spouse wants to get around while reducing their carbon footprint, these models add a little extra power to the equation. Whether they're riding a few blocks over for a New Year's party or riding for exercise, even in a neighborhood made entirely of hills, an e-bike lets your loved ones go faster with less lag or strain.
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.
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.
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.

Elon Musk had a good 2018, at least in retrospect. Coming out of production hell, Tesla’s Model 3 is now the #1 selling car in the USA by revenue, along with various other signifiers that Tesla is now a real, high-volume car manufacturer. Tesla itself declared a $300 million USD profit for Q3, delighting the stock market and its investors, if not the many shorters who continue to lose money and credibility.
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]
