Electric Tricycle for Adults, 750W(Peak 1350W), 48V13Ah Ebike, 20″x4.0″ Aluminum Folding Fat Tire 3 Wheel Electric Trike, Max 20MPH Hydraulic Brake, Rear Motor Differential by NARRAK

Assembly – The trike arrived in excellent condition. User manual print is a good size, but pictures could be larger. Still, it’s in good English and easy to follow. It took me only a day’s time to un-box, read the manual and finish assembly with provided tools. After that, I ran it with rear wheels raised off the floor, using the display selection switch (left handlebar) to help me learn to run it, simulator fashion. There are a large number of running options, but I’ll just discuss the ones most important to off-road use here.
Design – 1) There are four drive options: 750 watt motor-only, manual pedals, pedal assist (PAS) in five speed ranges up to 20 MPH, plus “walking mode”. 2) “Walking mode” speed is 1.9 MPH (less on a steep grade) by my display. 3) Peddling in PAS starts the motor, or you can twist the throttle slowly to run (factory default allows either). 4) Pedals (right axel) and motor (left axel) connect on opposite sides of the differential. In PAS, if one wheel loses traction, the other wheel stays fully powered. But when using only pedals or motor, just the wheel on its own side of the axel has full power: the differential acts like a “slipping clutch” to send reduced torque to the other wheel. 5) The 4-inch wide tires are good on wet surfaces and up to 3 or 4 inches of snow. 6) I’m 83, and the trike weighs 110 lbs., but I can lift the front or back halves to move it, go up steps or get it into my truck with ramps after I lift the front wheel to the tailgate. 8) The trike is 5ft 9 inches long, so fits in my 6 ½-foot pickup bed without folding.
Off-Road – 1) Lock the brake when parked. 2) Ride clear trails if possible. Debris or weeds can jam up the trike’s 7-speed derailleur near the ground. The motor drive is higher, so motor-only is OK to use, but only the left wheel will have full power. 3) To allow PAS mode and full power to both wheels, I mounted a plastic apron below the drives for protection. 4) PAS is critical in snow, and on uneven or very steep trails. 5) Speed settings are actually power levels. For very steep trails, use high PAS numbers. 6) Don’t expect fast acceleration out of this trike – it’s more like a tractor than a race car, but it runs silently: great for not disturbing nature. 7) You’ll get a good workout peddling uphill if you’re not really fit. But add the motor via PAS mode, and it’s a breeze. 8) I recommend this trike. I’ve seen no other E-trike in this price range that’s as well suited for my needs. Enjoy your rides and be safe!

Update, May 20, 2025: My bike motor stalled out on me at a slope of around 15 degrees, or 25% (front wheel approximately fifteen inches above the rear wheels) Then flipped over backwards when it began backing down the hill before the brakes stopped it. It ended up resting on the back wheels and back cargo basket, with the front wheel straight up in the air. It had a fully charged battery, but the grade unexpectedly steepened before I could adjust above PAS-1 used on the previous level ground. I suggested in my original review that a higher PAS level should be used at steep grades. My bad in this case, for being in PAS-1. The situation was initiated by applying the brakes, which automatically disengaged the motor prior to full brake activation, and caused the bike to travel backward during the pause that occurred before the brakes locked. Stopping the backward momentum on the steep grade sent the front wheel straight up at this point. The bike ended up with only dented rear fenders, but I was laid up for a while.

I no longer recommend the bike for off-road use due to no flip-back protection or brake that avoids reverse travel when stalling or needing to stop on a steep grade (such as approaching an obstacle, or to safely allow for trail traffic, etc). Personally, I’ll continue using the bike off-road, taking care to use higher PAS setting prior to attempting any significant slopes, and after adding an anti-flip device at the back of the bike (like many electric wheelchairs use), a mechanical brake, and by lowering the handle bars adjusted to a greater downward angle to allow lowering my body forward and lower while going up high grades.

I’m keeping the high original rating for use as shipped: on pavement, for which it is advertised, and for the helpful people at Narrak. But for safety reasons, keep it off steep slopes in offroad use. It definitely isn’t built for that.

I have 4 BIG dogs and am no longer able to walk them as
long as they need to be walked. An etrike, because of the stability, was the answer. This trike is well made with what seems like quality components. It was super easy to put together.
It had a comfortable ride and plenty of power. I like the fact the seat has a back on it for some lumbar support although the seat bottom was a bit hard. No kidding, there is a very real possibility of blisters on your bum if you overdo it too soon! The option of an upgraded seat would be nice. Larger rearview mirrors would be nice as well. These complaints though are easily fixed though.
I had such fun riding the the bike and my dogs love it! The largest dog is 100# and when he zigged as I zagged the bike hardly moved. Very good stability. Smooth riding over gravel and asphalt back roads. I was pleasantly surprised how easy it is to pedal without the power assist. It was nice to have the power assist when those darn little dogs came out to chase me. I easily left them in the dust.
I think the price for this bike is exceptional when you look at many of the other offerings out there.
It does NOT have a reverse gear or a parking brake if you are looking for those features.
I highly reccomend this bike.
