How this e-bike scores for different riding styles

High Performance
88/100

Excellent 1000W motor power and 36 mph top speed put this in the high-performance category. The upgrade 3-mode controller with Hall/Non-Hall capability ensures sustained power delivery.

Off-Road Adventure
72/100

The 1000W motor and fat tire compatibility provide excellent power for trails and rough terrain. Front suspension and high speed capability (36 mph) make it suitable for adventurous riding.

Recreational Leisure
60/100

The pedal assist system and multiple riding modes offer comfortable leisure riding options. However, lack of integrated battery and lights limits casual convenience.

Daily Commuting
45/100

As a conversion kit without battery included, this lacks the all-in-one convenience needed for reliable daily commuting. The 220 lb weight limit is also restrictive for carrying work gear or groceries.

Cargo & Utility
35/100

The 220 lb maximum weight capacity is below average and insufficient for serious cargo hauling. The powerful motor could handle loads, but the weight limit is a significant constraint.

Compact & Portable
15/100

This is a conversion kit for 26-inch bikes with no folding capability. It's designed to upgrade existing bikes, not provide portability or compact storage solutions.

Our Verdict

This PEXMOR conversion kit is like a turbo booster for your regular bike. For just $165, you get a really strong 1000W motor that can zoom up to 36 miles per hour - that's faster than most complete e-bikes that cost way more money. The kit comes with everything you need to install it yourself, including an LCD screen that shows how fast you're going and how much battery you have left. The pedal assist feature is really helpful because it makes pedaling easier, especially when you're tired or going uphill.

This kit works best for people who already have a 26-inch bike and want to make it electric without spending a lot of money. It's perfect for folks who like tinkering with bikes and don't mind doing some assembly work. The fat tire compatibility means you can use it for fun trail riding or beach cruising. If you're someone who enjoys high-speed thrills or needs extra power for hilly areas, this motor has plenty of muscle. The smart controller is a nice touch too - if something breaks, it automatically switches to backup mode so you can still ride home.

However, this isn't a complete e-bike solution. The biggest catch is that it doesn't come with a battery, which you'll need to buy separately for another few hundred dollars. That bumps up the total cost quite a bit. The 220-pound weight limit is lower than most e-bikes, so bigger riders or people who want to carry heavy bags might have problems. There are no built-in lights, so you can't safely ride at night without adding your own. The front wheel motor design can also make steering feel strange and might slip when climbing really steep hills. If you want something ready to ride right out of the box with all the safety features included, you should look at complete e-bikes instead.

What We Like

  • Super powerful 1000W motor that can hit speeds up to 36 mph - way faster than most e-bikes
  • Really affordable at just $165, making it one of the cheapest ways to turn your regular bike electric
  • Smart controller that keeps working even if parts break down by switching to backup mode
  • Works with fat tires for riding on sand, snow, or bumpy trails where regular bikes struggle
  • Includes LCD screen to see your speed and battery, plus pedal assist to make riding easier

What Could Be Better

  • You have to buy the battery separately, which can cost several hundred dollars more
  • Only handles riders up to 220 pounds, which is less than most e-bikes can carry
  • No built-in lights so you'll need to add your own for night riding
  • Front wheel motor can make steering feel weird and may slip on steep hills
  • Missing safety certification (UL) that shows the bike has been tested for electrical safety
