Meeting at University whilst studying Electronic and Electrical Engineering, we realised that we were both active individuals with a shared interest in outdoor sports and anything with two wheels. Combining our engineering knowledge and our years of experience with skateboards, scooters, bikes and more, we feel that we’re in a great position to test and understand these products and provide you with an unbiased, accurate source of information. 
It is not a off-road motorbike with an electric engine and a throttle. Electric mountain bikes have motors that only work when you’re pedalling. The motor tops-up your pedalling input. It’s called ‘pedal assist’. There are differing levels of assistance (called things like ‘eco’ and ‘turbo’) that you select via a handlebar-mounted control unit. The motor also cuts out once you reach 25km/ph (or faster). There are strict limits on the power of electric mountain bikes; 250w is the maximum nominal power. More powerful than that and the bike requires tax and insurance (like a car/motorbike) and is also not allowed on bridleways at all.
It was easy, good tools were shipped with the bike. The instructions are nearly useless, though. Like other reviews state, the front fork is backwards in the picture and shipped backwards. The disk brake should be on the port/left side. Flip the handlebar clasp around and leave the dirt guard facing forward. All the cables should flow naturally this way. Pedals were ok to put on, one of the pedals took a minute to get threaded but eventually got tightened.
their other models may have the same issue … This model comes to mind https://www.walmart.com/ip/ANCHEER-Folding-Electric-Mountain-Bike-with-20-Inch-Wheel-Large-Capacity-Lithium-Ion-Battery-36V-250W-Premium-Full-Suspension-and-Shimano-Gear/250514812?wmlspartner=wlpa&selectedSellerId=10813&adid=22222222227128420528&wl0=&wl1=g&wl2=c&wl3=235191079813&wl4=pla-578827040352&wl5=9012089&wl6=&wl7=&wl8=&wl9=pla&wl10=117084435&wl11=online&wl12=250514812&wl13=&veh=sem

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.

Everything arrived in perfect condition with minimal assembly. It took a moment to figure out where the headlight goes, and the rear reflector has a bike-seat (not a frame) mount, but I didn't even need the instructions. (Good thing, because the "instructions" suck. Find a video instead.) That said, if you buy this, pay attention: as others have noted, the front disc brake will be on your LEFT side when you're done (the fork is reversed for packaging purposes).
Overall, you’re not going to get a foldable electric mountain bike that’s better than this at the price that Ancheer are selling it for. It’s well built and designed, it’s easy to use and put together and it makes mountain biking so much more fun whilst opening it up to more people. If you’re looking for a versatile e-bike that is just at home on the mountain as it is on the morning commute, all for waaay less than $1000 then this might just be the bike for you.
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.
The gears don't seem to keep up on this bike. There are 21 gears, same as my other bike, but there is much more resistance at the highest gear on my other bike going 20mph than there is on this bike. The reason that is an issue is that during pedal assist, the bike goes pretty quick and I don't want to be pedaling air, I want some, just a little, resistance. I don't know the mechanics of it or how this would be the case, perhaps because this bike has smaller wheels than my other bike? The bike came pretty well adjusted on the derailleurs. I haven't touched the back but the front I've had to mess with a little. The chain fell off outboard once, so had to adjust. Chain guard did its job well. The chain got stuck pretty good, but once I loosed the chain guard everything was easily moved.
The bike comes partly disassembled for shipping, so you'll have to attach the handlebars, pedals, front light, quick-release saddle and front wheel. In all, it'll take you around 30 minutes including removing all the cable ties and packaging. The tools to do this are included, but you might prefer you use your own screwdriver and spanners as the supplied tools are poor quality.
Rented a pretty decent Scott. Did some nice mixed terrain but only for a day. Firstly it was great fun. Hard to get away from that. The pedalling felt good. It was like everything was a slight downhill. You can pootle or give it a few hard pedals and fly along at any time. On the flat, uphill, on bumpy grass, all felt like downs once you pedaled a lttle. Good connection between the pedalling and the movement. Smooth delivery. It just took the terrain and slope out of the equation. Could’ve easily got away with less power. It would be an expensive buy. This one was 3.5k but kitted out like a £500 halfords special. Once the price comes down they will be everywhere.
With three levels of assistance, the the ANCHEER Power Plus lets you enjoy a fun and easy ride every time . If you want to reach your destination without breaking a sweat, the Pure Electric Mode or full throttle mode will give you the full power you want. But, if you want a light cardio workout but with a little assistance, use the Pedal Assist Mode. Want the feel of a traditional bike? Use the Regular Bike mode.
