The 13amh battery is nestled at the down tube frame on a battery bracket, which you can remove quickly if required. The battery is powerful enough to provide life juice to the bike for a long distance. The trip distance is 25 miles in full electric mode and 50 miles on the assist pedal. The battery comes with a 48V 2.0A charger and it survives more than 500 times of recharge cycles.

The bike has a maximum range of 20 miles before needing to recharge.  Keeping up with speed and battery life is a breeze with the Bafang LCD display that comes standard with this model. A durable aluminum alloy frame helps this bike take a beating and keep on going. The Stalker has an 8-speed transmission and a set of Tekro mechanical disc brakes that will give you full control over the bike. A pair of 20 inch by 4 inch tires will help you climb those steep hills and easily get down those muddy trails. 


I bought an electric bike mainly for hunting purposes earlier this year. Due to the motor size of 750 watts, it is not considered a motorized vehicle like a motorcycle where I live in the Rocky Mountains. No idea what the regs are in other states. It is considered a bicycle and can therefore be used just about anywhere on public land. Great way to go when you are covering tens of thousands of acres. Going from a week to a day to cover one of the ranches I hunt.

To help the rider find the perfect fit, the stem is adjustable. The bike also boasts dynamo powered lights alongside hydraulic disc brakes. The bike will suit riders from 4 ft 10 to 6 ft 5, and also integrates with a child seat. The total weight is 22.5kg, making it admittedly a fairly hefty folder – but that’s fairly uniform across electric versions.


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.

UPS delivered one day later than the expected delivery date. It was a little frustrating, but one day is just one day, so can't be all too upset. Box arrived in good condition. Inside the box, the bike seemed to be packaged well but there were issues. The left gear shift handle was snapped off. Homdox was notified and they said they would send a new one (handle, gear shift, bike.... not sure, assuming a new gear shift).
As I said before, going up hills might require some pedaling, but it is SO MUCH EASIER with the motor running. I feel like a higher voltage is used on level 3 pedal assist than can be gotten just using the hand turn, though. It takes a few pedals for the pedal assist to kick in which can be annoying, but it does save some battery on initial acceleration. You also have to be careful pedaling around to park the bike or at a street corner waiting for traffic because you DO NOT want the motor to kick in and send you into a workbench or worse ... oncoming traffic.

The adjustable front shock offers smooth cushioning and buffers the jerks when cycling on uneven surfaces. However, the rear shock is rigid and hard to move. The Shimano 21-gear shifters will allow you to enjoy great speed with a maximum of 20mph. But, it would be better to have at least 24 gears at that speed, because you will feel almost no resistance when cycling at the max speed in the highest gear.
Other than your battery indicator all other info is shown on your display. In terms of position of display it looks ok. You can scroll around using +/- buttons on left side of your handlebar. It isn’t super ergonomic but still better than Haibike in terms of ease of use. The display can be removed so you won’t need to worry about it when you park your e-bike outside.
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 newest electric mountain bike from Ancheer provides the joy of mountain biking with some advanced features that make it more enjoyable and let the riders to have the control of their rides. At less than $800 price and with mid-range features, it may not compete with the XF800 or BAFAG models, but it provides good value for the money, nonetheless. What is the best electric mountain bike?
