Bulls E-Stream Evo AM 4 27.5+

(1 customer review)


What’s the point in having a bike that helps you go farther and makes you want to stay out all day if the battery isn’t up to the task?

Welcome to the endurance steeds of the BULLS eMTB line-up. The all new, all-mountain E-Stream EVO AM series boast the new Brose Drive S Mag motor, smaller and lighter than the previous generation, with even more power and torque. But, what really sets this eMTB apart is the BULLS Supercore battery- 1 battery. 750Wh. That’s and optimal range of over 150 miles. As if that weren’t enough, both models are complete with Fox Float Rhythm 150mm front and rear suspension.

    I have really been enjoying riding this bike. First of all, the geometry is well suited to control in the downhills, and feels solid climbing as well. The dropper and suspension work well to achieve a really plush riding experience. Where the bike really shines is the motor and battery combination. The battery has range in spades – in my experience, with 2000′ climbs being an everyday experience, I still end up with 60-80% remaining after a ride. The motor is almost seamless and nearly silent in providing support – as others have said, this motor feel is very much like riding a bike compared to a Yamaha or Shimano motor (both of which really pour the power on when you ask for it – and usually, you can hear it). In comparison, the Brose is very smooth, and provides the support you need, without necessarily providing motorcycle like thrust. That being said, at max support, or in low gear, the significant additional torque this motor has really lets itself be known – you won’t have any trouble getting up hills. In fact, on ridiculously steep hills, in low gear and top support, you will need to focus on keeping the front wheel on the ground. However, I really like the more subtle feel of the ride on this bike in the other support settings, which lets you concentrate on your riding skills, instead of modulating raw thrust. Finally, when the speed exceeds the top support speed of 20 mph, the power feathers in and out very subtle, avoiding a feel of drag and weight – it is just a smooth ride. Overall, a very nice ride.
