Which is better for a heavy adult tricycle?

The KEARIXM's 750W motor has more power on paper, but the E-BikeKit includes a matched 48V 15Ah battery and controller, so it is the safer complete package. Check your trike's weight and dropout spacing before choosing.

Do I need to buy a battery for the KEARIXM kit?

Yes. The listing does not include a battery, so budget for a 48V pack on top of the $102.83 price. The E-BikeKit price of $168.99 at Amazon already includes one.

Which kit is easier to install?

The E-BikeKit front hub wheel replaces your front wheel and keeps the rear axle and drivetrain untouched. The KEARIXM is chain drive, which usually means more drivetrain work.

Is the E-BikeKit worth about $66 more?

Yes if you need a battery, display and pedal assist sensor, since those add up to more than the difference. No if you already own a 48V battery and just want a motor.

Which has a higher top speed?

The KEARIXM lists about 13.67 mph. The E-BikeKit does not state a top speed, so compare controller settings and local e-trike rules.

Will either fit my wheels?

The KEARIXM is listed for 26-inch wheels. The E-BikeKit uses a 100 mm front dropout and a hand-built front wheel, so measure your fork spacing first.
