  • Battery: Bosch PowerTube 500
  • Bike Weight: 33.5lb

The Diamondback Response runs on a 500Wh PowerTube battery and a Bosch Performance Speed motor, making it lightning quick. You can pedal up to 28 miles per hour on this Class 3 electric bike with this motor.

The 500Wh PowerTube battery offers a good range, and the motor responds smoothly to your pedaling without being overbearing.

It’s also one of the most extensively serviced drive systems on the market, so if anything goes wrong with your drive system, the chances are strong that your local bike shop will be able to help.

For people whose commuting involves curbs, bumps, and rolling up and downstairs, the Diamondback Response is perfect for them.

Alternatively, if you want a steady, well-handling e-bike that can comfortably travel at 28 mph, it is still a great bike for you.

Even though it is just above our $4,000 range, the Response is a great mix of off-roading technology and smooth electric biking that can get you to work quickly without making you sweat and can also do wheelies and other crazy stunts along the way!

3. Aspen Plus Fat Electric Bike by NCM $2,299

  • Motor: Das-Kit, X15F, 48V 250W, 25km/h
  • Battery: i5-4816P, 48V 16Ah, 768Wh
  • Bike Weight: 67 lbs

As with their other models, the NCM Aspen fat tire electric bike appears to offer outstanding value without making sacrifices on the construction quality.

The Das-Kit 500w geared rear hub motor of the NCM Aspen is paired with a respectable 48v 13Ah lithium battery pack on this bike.

Despite the 500w stated output, this rear hub motor has a maximum output of nearly 700w, which is more than enough power for tough and wet terrain. Das-Kit is NCM’s in-house brand.

The 13Ah battery provides a realistic range of 25-35 miles, depending on how often you use the throttle.

Increasing your reliance on the throttle can restrict your driving range further. If you use the e-assist sparingly, you can get over 50 kilometers of range on a single charge.

Even though it’s a decently large and weighty bike, the electric motor has plenty of power to handle the slick, muddy terrain it’ll be riding through.

You will have a driving range of 35 to 75 miles depending on how hard you pedal with the Specialized 320Wh down-tube battery. However, a 160Wh range extender battery ($430) is available as an add-on.

This e-bike is incredibly light! Weighing in at only 36.9lbs even with the additional weights of added fenders, a rear rack, and lights.
