Bosch’s flagship mountain bike system uses a mini drive ring with internal gearing to send its power to the drivetrain. There’s some resistance in the system over 25km/h, but when you first press down on the pedals there’s an impressive surge of power, and it offers good support over a wide cadence range. Its size has an impact on the width of the cranks (the Q-factor) as well as the chainstay length of the frame, and it’s not the lightest system on the market at 4kg for the motor. On the other hand, Bosch is the most established player on the market, and its system has proven itself over many years.
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
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).
I’m sure the can of worms has already been opened on this subject… Oh it’s motor bike blah blah they should be banned, is this whining mostly from strava whippets who’s times might be beaten? I raced motocross for 12 years & they are motorcycles with a internal combustion engine and yes they do make a mess of the country side but on land that has been allowed & nowadays has planning permission to be used for such events.
The suspension works, but there isn’t any true dampening. Ancheer Electric Mountain Bike - That means you’re just riding around on springs. On a real full suspension e-bike (i.e. a few thousand dollars) you get actual oil-dampened shocks. Those absorb bumps and dampen the shock. With springs, the bike bounces a few times after bumps, with the energy dissipating through the spring stretching and compressing.

With 170mm travel, aggressive angles and Shimano’s superbly calibrated STEPS motor, the Focus Sam2 is an enduro bike with a built-in shuttle. With the bolt on TEC pack you really can climb to new heights, but without it the smaller capacity internal battery means you need to be ultra economical with your energy use. It’s also frustrating that the internal battery can’t be removed easily for charging. By far the biggest frustration with the Jam2 though is that the sizing isn’t very generous and standover clearance is limited. It’s still a great e-bike, but when you’re spending this much money, you can afford to be fussy.
My wife has a Scott, essentially a Contessa with a Bosch crank motor. Very heavy thing, bloody hard work with no assistance, but even with assist on progress surely depends on your effort. We don’t do a lot of trail centres, but it’s been fine round Rothie, up to Einich, in Inshriach and up the Corbett behind Kingussie, as well as onroad. Lets us ride together, which would be harder without assist, and is heling her recover from skiing injuries.
I haven't given a full benchmark on battery life as I haven't gone without pedaling just using the motor. I live in a hilly place and I need to pedal to make it up some hills. But initial impressions are good. My hilly trip to the beach with kids in tow was about 13 miles round trip and I made it down to 3 of 5 bars on the battery. The battery does go down when the motor is under stress but levels itself when back on level ground. Battery is looking good.
Why We Like It: SwagTron is a company known for producing quality electric personal transportation device. I can confidently say that the SwagCycle EB-5 Pro lives up to their quality standards. This is a great little bike for tooling back and forth around your campus or any other situation where you have to go to and fro a lot. With a comfortable speed of 15 MPH and a weight limit of 265 pounds, this is a reliable bike for beginners of almost any size. It has a range of 15.5 miles. Not the furthest, but a great range for new riders.
Why We Like It: This is the best electric folding bike for 2019. It has great features along with portability. The ANCHEER Folding Electric Bike is the bike that we tested. We love that the bikes battery can be removed. It performs great, has a comfortable speed, decent range and is light and durable. The only minor issues we had are that the headlight is made cheaply and for the speed/range we felt that it should charge just a bit faster.
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 Ancheer Folding Electric Bike is a great product at a great price. It’s pretty good looking, despite the slightly cumbersome battery pack attached to the frame. It has a wide range of features, is very easy to use and comes mostly assembled. The ability to fold it down for easy transport and storage just adds to the versatility and practicality that the bike already has. Ancheer are also said to have a great customer service team if there are any problems. Best of all you get all of this for way less than a $1000. Most quality e-bikes now a days will easily set you back $1000, sometimes several times more.


The fit is a little rough for me. I'm tall, about 73 inches, and I feel like the bike is small. I've ridden a few dozen miles to include a trip with a kids trailer towed behind, and it hasn't been really uncomfortable, but a little cramped compared to my Schwinn Trailway 28"/700c hybrid bike. Seat adjusts up but feels tilted back a little more than I would like. I have ridden in shorts and tshirt to the beach as well as khakis and a button up with backpack to work, ok comfort both ways. Perhaps it will just take some time to get used to.
If you really want to see the future take a look at the Fazua Evation, with a battery and motor this system weighs an incredible 4.7kg! The battery only has 250wh, but at 1.3kg you could easily carry a spare in a pack. The really interesting thing about this system though, is the motor and the battery can be removed from the frame, so you really do have two bikes in one.
Why We Like It: The Elby 9-Speed Electric Bike is our top choice because it is loaded with features, has a quality build and an outstanding 90-mile range on a full battery capacity when you pedal a bit to assist it. Welcome to the modern bike world.. This E-Bike is the top one as it offers a powerful motor, a high weight limit and a ridiculous range.
Amazing bike, quick. On the flat average 21mph full power, after 3-4 miles average 18mph. A lot of hills in SoCal so this 1/3 hp motor does it’s job well with pedal assist on very steep grades. With electric only mode and heavy, steep, long hills this bike does its job pushing through a 16 mile commute with some energy to spare with a 190lb load of me and my gear. This bike could do much more with flat and pedal assist modes maybe twice as far. Recommend you use smaller tires 1.75 vs the standard 1.95 to achieve my results. Continental contact travels work great!
Yep, there’s no getting away from the fact that i’m peddling a 21kg bike when the assist is switched off but with the massive battery & range there is no real need to switch it off, I can barely turn the pedals on a normal bike when i hit a hill so if i’m on the road and wanting as much range as possible to explore a few of the surrounding trails in my area of Galloway i’m quite happy using the eco mode to get myself around, the tour mode gives a bit more assist and is enough to tackle the majority of single track climbs with effort from myself, the sport mode is enough for all but the steepest of singletrack use and the turbo mode is just batshit mental for all out super steep climbs and so much fun.

I’m sat here absolutely knackered after being out this morning for a 3hr session round my local trails, including some much needed trail work which is quite amusing as i tend to stumble and fall on my arse quite a lot but over the past month i have managed to clear pretty much all of my old trails with the aid of a flask of tea, quality tunes on my jambox speaker along with my rake, mini shovel and Silky Zubat saw – I’ve managed to regain that totally exhausted feeling you get at the end of a days riding n” trail grooming so i’m a very happy bunny indeed! – albeit sitting here with aches n’ pains that make me wince if i reach for anything but i wouldn’t have it any other way. 

I continued to have issues with the rear brakes. The rear disc brake was bending when I braked and I could not figure out how to get it from rubbing on the pads. I eventually took the bike over to REI and paid for a tune-up. Fantastic work by them, the bike has a better top speed by a couple mph now and shifting/braking are much smoother. I was also having issues with the chain jumping off the front derailleur on high torque (high gear from standstill). Looks like I just needed the experts to give it the tune.
