How this e-bike scores for different riding styles

Off-Road Adventure
85/100

The 750W motor with 20° climbing capability, 4.0" fat tires, and front suspension make this excellent for trails and rough terrain. The powerful motor and all-terrain tires excel in off-road conditions.

Recreational Leisure
82/100

The comfortable fat tires, thickened seat, and 45-mile range make this ideal for casual beach rides and neighborhood cruising. Three riding modes allow riders to adjust effort level for relaxed rides.

Daily Commuting
78/100

With 45-mile range and 20 MPH speed, this bike handles daily commutes well. The integrated lights and LCD display add practicality, though the 69.5 lb weight makes it less portable for multi-modal commuting.

High Performance
65/100

The 750W motor and 20 MPH speed are respectable but not exceptional for performance enthusiasts. The 20 MPH speed limit is below high-performance standards, though the hill-climbing ability is solid.

Cargo & Utility
45/100

While the 750W motor provides hauling power, the lack of rear rack and missing max rider weight specification limits cargo assessment. No fenders also reduce practicality for utility use in various weather conditions.

Compact & Portable
20/100

This bike is not foldable and weighs 69.5 lbs, making it impractical for apartment storage or public transit. The 56.3" length also requires significant storage space.

Our Verdict

The OTD DS2 electric bike offers solid all-around performance at a budget-friendly price of $399.98. The 750W motor provides plenty of power for hills and trails, climbing up to 20 degrees which beats most bikes in this price range. You get 45 miles of range from the big 624Wh battery, and the fat 4-inch tires grip well on sand, snow, and dirt paths. The bike comes with important safety features including UL 2849 certification, integrated lights, and a password lock. The LCD display shows your speed and battery life, and you can switch between three riding modes depending on how much help you want from the motor.

This bike works best for people who want to ride on trails, beaches, or rough roads without spending a fortune. If you like exploring dirt paths or riding in snow, the fat tires make this a great choice. It also works well for casual neighborhood rides and short commutes where you can charge it at home or work. The strong motor means you won't struggle on hills, and the comfortable seat plus fat tires smooth out bumpy roads. People who live in houses with garage space will appreciate this bike since it's easy to store when you have room.

However, this bike has some clear limits. The 20 MPH top speed is slower than bikes that go 28 MPH, so it's not the best if you're in a hurry. At almost 70 pounds, it's really heavy and hard to carry up stairs or lift onto car racks. It doesn't fold up, so forget about taking it on the bus or storing it in a small apartment. You also miss out on useful extras like a rear rack for carrying stuff, fenders to keep you dry in rain, and a USB port to charge your phone. If you need to carry cargo, go faster than 20 MPH, or store your bike in tight spaces, you should look at other options. But for the price, this is a solid choice for recreational riders and weekend adventurers.

What Could Be Better

  • Top speed of 20 MPH is slower than many e-bikes that go 28 MPH or faster
  • Weighs 69.5 pounds which makes it hard to lift upstairs or load onto a car rack

  • Missing useful extras like a rear rack for groceries, fenders for rain, and USB charging port
  • Only has front suspension so bumps still hit hard on your rear end and back
