Product Review Summary

First, let's talk about speed. The Asomtom E300 has a 750 watt nominal motor and a 48 volt 15 amp hour lithium battery. According to the manufacturer's website, it has a top speed of 31 miles per hour. In my testing, I found that the bike's pedal assist levels corresponded to the following speeds:

Level 1: 10 mph (on the app) / 12 mph (on the bike)
Level 2: 12 mph (on the app) / 15 mph (on the bike)
Level 3: 15 mph (on the app) / 17 mph (on the bike)
Level 4: 17 mph (on the app) / 25 mph (on the bike)
Level 5: 25 mph (on the app) / 28 mph (on the bike)

I also tested the bike's half twist throttle and found that it had a top speed of 25 mph. One thing to note is that the throttle will engage a cruise control function if held at a certain speed for a few seconds.

In terms of acceleration, I found that the Asomtom E300 had a gentle start from a standstill, but it picked up speed quickly once it got going. The bike also had a quick reaction time for both pedal assist and throttle modes.

Next, let's talk about the bike's climbing abilities. The manufacturer claims that the Asomtom E300 can climb up to a 35 degree slope, which is equivalent to a black diamond ski slope or a 70% grade. While I didn't have a 35 degree slope to test on, I did ride the bike up a 15% grade hill and found that it performed well, although it did slow down towards the top.

Finally, let's talk about range. According to the manufacturer, the Asomtom E300 has a range of 15 to 30 miles, depending on the rider's weight and the terrain. In my testing, I found that the bike had a range of about 18 miles on a full charge, with an average speed of around 15 mph.

Overall, I was impressed with the Asomtom E300 fat tire electric bike. It has a good top speed and quick acceleration, as well as solid climbing abilities and a decent range. It's also a step-through design, which makes it easier to mount and dismount, especially for smaller riders. With a weight capacity of up to 400 pounds, it can accommodate a wide range of riders.
