It wasn't all gold stars for the Bulls, however, as the larger battery storage of this bike makes it the heaviest in our test. This heavyweight rig is far from nimble or agile, giving it a more one-dimensional performance on the descents, and hampering its climbing abilities in technical sections or tight corners. Its charging port is also recessed into the frame making it one of the least user-friendly, and while we did like their e-bike controls, they couldn't quite match the ergonomics or display of some of the competition. Overall, we had a blast riding the E-Stream EVO AM 4, read on to find out how it compares. 

The bikes we tested all use a different e-bike motor system, and the controls, the primary user interface, are an important element we rated but didn't weight as heavily as some of the others. Each motor system and its associated controls are slightly different. Our primary interest is in how user-friendly is it to interact with the system, how intuitive and ergonomic are the shifters, how good and easy to read is the display, and how easy is it to charge the battery? Each drive system also has a smartphone app that is intended to allow the user to fine-tune the motor's support settings, create custom settings, monitor battery charge and health, and a whole lot more. We don't feel the apps are necessary for the use of any of these e-MTB's, but those with an affinity for technology or personalizing your ride may be inclined to use them.
I received my ALL TERRAIN 750 right before my month long Colorado archery deer and elk hunt. I was able to quietly get in to places in 15 minutes that used to take me over an hour to hike in! If you are a serious hunter that wants to get away from the crowds to hunt then you NEED one of these bikes. I did a ton of research and comparing and M2S hands down has the best bike / customer service for the price, period! 

Mountain biking is all about having fun, right? About getting out there, enjoying the great outdoors, exercising your body and freeing your mind. So what if we told you there was a type of bike that lets you ride further, faster, and have even more fun? One that even made you LOL on the climbs? You’d still have to work for your rewards, but by assisting your efforts, it allowed you to wring every little drop of enjoyment out of your rides.
Trek Bicycle Corporation is one of the worlds largest bicycle manufacturers operating in North America, Europe and Asia. The company was founded in 1976 and is headquartered in Waterloo Wisconsin USA and includes multiple subsidiary brands (Electra, Gary Fisher, Diamant and the Bontrager parts label). Trek offers an industry leading warranty and provides service through more than 1,700 dealers in North America making them one of the easier brands to test ride and get ongoing service for. They were one of the first big brands to offer an ebike in the US relying on BionX drive systems and have since expanded their lineup using Shimano and Bosch systems.
The frame is solid. In fact too solid for me. The frame is thick with such a girth that my rear wheel bike rack doesn't fit (around the frame or into the pre-drilled holes because the disk brake is in the way). Shocks seem to work fine. I do enjoy having the kick stand further back, provides a lot more stabilization to the bike vice being closer to the pedals.
In our head to head range test, the Rocky Mountain took the win by traveling 20 miles and 4,297 vertical feet. It is worth mentioning that our tester felt that he worked a little harder while range testing the Rocky Mountain than the other bikes we tested. The Giant wasn't far behind at 19.02 miles and 4,000 vertical feet, and the YT Decoy almost tied that with 19.01 miles and 4,039 vertical feet. The Specialized was nipping at their heels with 18.71 miles and 3,949 feet. The Ghost Hybride SL AMR was the least impressive with a range of just 16.75 miles and 3,559 vertical feet. The outlier in this comparison is the Bulls E-Stream with a 650Wh battery. We were not able to test the Bulls directly against these other competitors, but we did notice that you can ride it significantly farther than any of these other contenders. During one of our test rides, we rode the Bulls 24 miles and 4,500 vertical feet, and the battery still wasn't depleted. More battery storage equals longer rides; it's just that simple. 

It is a great e-bike which has a PAS feature. This means, that the bike is secure enough for riding for beginners and the motor is adjustable to your needs. It is a lightweight and simple e-bike.  The price is really astonishing for normal size electric bicycle. Another thing to mention Jasscol has disc brakes which are not so common on cheap bicycles.

After you decide which style of e-bike you want, consider the class. In the U.S., there are three classes defined by the type of assist and how fast the motor will propel you. Most electric bikes sold are class 1 or 3. Class 1 bikes have a motor (max 750w) that assists while you’re pedaling, up to 20 mph. Class 3, also known as “speed pedelec,” can also have up to a 750w motor, but it can assist you up to 28 mph. Both are allowed in most states and cities without requiring a license. Class 2 models have throttles that don’t require the rider to pedal in order to get a boost. They’re allowed on most streets, bike lanes, and paths, but are less popular than the other classes and not covered much here (because not only do we still love to pedal, we also prefer the greater distances that pedal-assist bikes can cover).

This ultra-light frame provides greater strength to weight ratio. It makes the bike less cumbersome to carry and robust enough to take a beating on the rough trails. A weatherproof and rustproof finish used on the frame lets the bike retain its new look for longer. Carbon-steel fork provides excellent shock absorption to keep you comfortable on bumpy surfaces.
All the electric bikes need to have the best braking system to keep them safe for all users. With this quality E-bike, you are assured of a safe ride thanks to the front and rear disk brakes. This makes it easier to stop the bike even when at a higher speed. Besides this, the bike also lasts for years due to the high-strength carbon steel used in the construction. This makes it a great investment for anyone looking for the best electric bike. What's the best electric mountain bike?
