Time to give some love to my dudes and dudettes over at Bulls bikes. The Bulls E-Stream Evo AM 4 27.5+ (phew, out of breath after saying that one) is an incredible electric bike for the price point. I was going to put the step down from this bike on the list, (2018 Bulls E-Stream Evo AM 3 27.5+) but I realized that this bike is only $400 dollars more. The upgrades you get for that 400 bucks are pretty remarkable.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.

So go ahead, plan your next adventure or see where you daily commute will take you. With the AWOL, the only thing holding you back is your imagination.
With different degrees of assistance at your fingertips, riders of varying fitness levels are easily accommodated on the same ride too. Which, depending on who’s setting the pace, can bring a social aspect back to big days out, because you can all ride together and the assistance from the motor makes it that much easier to string a coherent sentence together even on the steepest climbs.
In the end, the Specialized Turbo Levo FSR Comp 6Fattie proved to be the tester favorite, offering the best downhill performance that felt the "most like a mountain bike" that the other models couldn't match. The Specialized proved to be the most nimble and agile by far, with the lowest center of gravity, shortest wheelbase, less rear wheel travel, and shortest reach, yet still managed to be confident and stable at speed. By contrast, the Commencal Meta Power Race 650B+, our Top Pick for Aggressive Riders, felt much more one-dimensional with its long and slack geometry and ultra plush suspension, excelling at speed, but sluggish at lower speeds or technical downhill sections. The HaiBike XDURO AllMtn 8.0 proved to be a less inspiring downhill performer, with a massive feel, rattling battery, and a generally unrefined feel, although it was good at going straight and fast. The Trek Powerfly 7 FS was our least favorite e-bike to ride downhill, with a less impressive component specification that held it back and didn't inspire confidence on descents.
In our view, e-bikes are approaching a crossroads in concept and design. Heading off in one direction are longer travel, enduro-style e-bikes, which are largely designed for cruising up and then blasting back down. Plotting a slightly different course is the idea of a lightweight model that rides much more like a normal mountain bike, but requires more work from the rider. Of the two approaches, both have their benefits, but it’s the latter that gets us the most excited. Once the overall weight falls into the 16-17kg range (the lightest bikes are currently19-20kg) it’s going to be really hard to tell the difference between an e-bike and a regular trail bike on the descents and the flat, but you get the benefit of a gentle push up the climbs.

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.

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,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] 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.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] 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.[72][73]

Weight isn’t anything like a critical as one would assume. Weight distribution however is a different matter and this is where geometry, specifically the ratio of the front centre measurement to the chain stay length really comes into play. Battery placement is important too, and smaller batteries give an edge in the handling stakes while robbing the bike of range.

“Rather than bolt on a bulky off-the-shelf system, we struck out on our own to redefine the category. The Powerplay system is the result of designing an electric drive for the suspension and geometry needs of proper mountain bikes; in fact, the geometry and pivot points of the Altitude Powerplay are identical to those of the new Altitude. In our opinion this is the first electric bike that actually rides like a mountain bike should.”

Over several months, our team of four professional mountain bike testers rode each of the electric mountain bikes in our test selection on a variety of trails and terrain in a range of weather conditions. We had each tester ride each of the bikes numerous times, often riding the different models back to back for the sake of comparison. We didn't go easy on them. Instead, we treated them all as if they were our own, putting them all through the wringer to identify their strengths and weaknesses. We scrutinized every aspect of each e-bike's performance and scored them all on several rating metrics, e-bike controls, downhill performance, uphill performance, power output, and distance range. Each metric are described in greater detail below. It is important to note that during our testing our impressions of these e-bikes changed dramatically. Our first impressions didn't exactly stick. It was essential for us to test the different models head-to-head and make direct comparisons to flush out the differences. For example, everyone was initially a little underwhelmed with the Specialized's power and more excited about the Haibike, but after hundreds of miles of testing our impressions changed. We go into more detail on this below.
It’s hard to ignore the growing popularity of electric bikes. Commuters and hybrid riders have already embraced the technology, but what about when it comes to mountain shredders? MTB fans are certainly beginning to realise the benefits of electric – an electric mountain bike can give you all the thrills you want from a normal MTB but with the extra power you need to get back to the top and give the trail another go.
Those are our choices for the top eMTBs this year. There are loads of great options as battery life continues to improve and motors provide more assistance than ever before. Electric bikes are primed to move heavily this year. It’s the only bike market that continues to grow every year. The more units that sell, the better the bikes become. That’s great for consumers and the bike community in general!
Descents on such a heavy bike are less fun. Getting the rear wheel off the ground on short notice, or whipping it around turns is very hard. I like to use my rear tire and brakes to steer—locking the brakes in tight corners at speed, then letting off and pedaling out. On very loose and exposed trails, using that approach on the Turbo Levo doesn't work, once the rear starts to loose traction, it’s just all over. Perhaps this could be combated with lower rear tire pressures; we were running 20 PSI. 
TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,...
Often times, carbon gets all of the attention, but as our Senior Advanced R&D Engineer, Chuck Teixeira, says, 'If you haven't ridden an aluminum bike lately, you haven't ridden an aluminum bike.' And the same reigns true for the Men's Chisel. It packs some serious XC-prowess into an aluminum frame, making it the most durable, value-packed XC bike out there.
Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle.[44][45] Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.[citation needed]
