RNNSNN Electric Mountain Bike with 1500W Peak Motor and 36V Battery

For adults considering an e-bike for commuting, getting around town, or weekend rides, the RNNSNN combines a claimed 1500W peak motor with a removable 36V, 15Ah battery. The listing describes it for city streets and light trails, with front suspension, seven speeds, an LCD display, and a USB port. Its stated range is up to 80 miles, so it may suit riders who want fewer stops on longer outings, though that figure is presented as a maximum rather than a guaranteed result.

It also has app-based settings and arrives 90% pre-assembled, according to the product information.

Key points

The motor is listed at 1500W peak and 80 N·m of torque, with a stated top speed of 22 MPH. There is an important detail to factor in: the manufacturer’s FAQ says the bike is set to comply with local regulations at 20MPH out of the box, and advises contacting the company for instructions on adjusting settings. That same FAQ mentions an adjustment to 32 MPH. Riders should base their decision on the bike’s supplied setting and the rules that apply where they ride, rather than assuming the higher figure is available by default.

The removable 36V, 15Ah lithium battery is claimed to provide up to 80 miles of range and take 4–5 hours to charge fully. Actual distance can depend on riding conditions, so the maximum figure is most useful as a reference point, not a promise for every trip. A G51 LCD shows speed, mileage, and battery information, while its USB port can charge a phone. App-based bike management is also listed, although the product details do not specify which settings or phone requirements it supports.

For a commute with occasional rough pavement or a light trail detour, the front suspension and the described combination of fork absorbers, seat springs, and pneumatic tires are intended to add cushioning. Seven speeds give riders another way to adapt to changing terrain. Compared with a basic city bike, this model adds electric assistance and more comfort-focused features, riders seeking a dedicated setup for demanding off-road routes may want to compare those needs against the listing’s stated use for light trails.

Practical tips

The bike is described as 90% pre-assembled, with a step-by-step installation video available on the product page. Plan to complete the remaining setup before riding, and use the manufacturer’s instructions for any changes to the speed settings. The stated 4–5-hour full charge time can help with planning between rides. The battery is described as removable, which may be useful when deciding where charging will fit into a daily routine.

The product information also states that the e-bike is certified to ANSI/CAN/UL 2849 and its lithium-ion battery to ANSI/CAN/UL 2271 by SGS. A limited warranty is listed, while the feature description specifies 12 months, check the applicable warranty terms for the exact coverage.

Getting the most from it

For a town commute, the display can make speed, mileage, and battery status easier to track, and the built-in USB outlet offers a way to keep a phone charged during the ride. On a weekend outing, the removable battery, front suspension, and claimed long range may be more relevant than top speed. It makes sense if your plans center on everyday riding and light trails and you value the added display and charging features.

Should you buy it?

This RNNSNN is worth considering if you want an adult e-bike with electric assistance, a removable battery, seven speeds, and features aimed at commuting and casual rides. The main point to weigh is the difference between the listed 22 MPH and the FAQ’s 20MPH out-of-box setting, the product information does not make that configuration identical. Not the best choice if your purchase depends on a particular speed setting being available immediately or on a stated maximum range being assured for every ride.
