How this e-bike scores for different riding styles

High Performance
75/100

The 1200W brushless motor delivers excellent power output, reaching the 'excellent' benchmark threshold. With 470 RPM capability and upgrade 3-mode controller with sine wave efficiency, it offers strong performance characteristics for enthusiasts, though specific top speed data is not provided.

Recreational Leisure
65/100

The three riding modes (throttle, pedal assist, manual) provide versatility for casual riding. The 1200W motor offers plenty of power for leisurely rides without strain, though the lack of included battery means additional investment is required.

Off-Road Adventure
60/100

The 1200W front hub motor provides substantial power for trails and hills, reaching 470 RPM. However, front-wheel drive is less ideal for off-road traction compared to rear-drive or mid-drive systems, and the 220 lb weight capacity limits heavy-duty adventure use.

Daily Commuting
45/100

This is a conversion kit, not a complete e-bike, requiring an existing bicycle. Without an included battery, it lacks the out-of-box readiness needed for reliable daily commuting. The powerful 1200W motor is suitable but missing integrated lights and display are significant drawbacks for urban commuting.

Cargo & Utility
35/100

The 220 lb maximum weight capacity is quite limiting for cargo applications, well below the 265-350+ lb capacity of dedicated cargo e-bikes. Front-wheel motor placement also reduces stability when carrying heavy loads.

Compact & Portable
20/100

As a conversion kit with a 26-inch front wheel motor, this offers no portability advantages. It's designed to convert an existing standard bicycle, not create a compact or foldable solution for storage or transport.

Our Verdict

This PEXMOR electric bike conversion kit is a budget-friendly way to turn your regular bicycle into an e-bike without spending thousands of dollars. For just $150, you get a really strong 1200W motor that spins at 470 RPM, which is powerful enough to zoom up hills and go fast on flat roads. The kit includes pedal assist and a twist throttle, so you can choose to pedal with electric help or just twist and go without pedaling at all. It also has brake levers that automatically stop the motor when you brake, which keeps you safe. The aluminum parts are sturdy and it comes with everything you need to install it yourself, including tools and instructions.

This kit works best for people who already own a 26-inch bike and want to make it electric without buying a whole new e-bike. It's great for weekend riders who want some extra power for fun rides around the neighborhood or local bike paths. The three riding modes mean you can save battery by pedaling more when you want exercise, or use full throttle when you're tired or going uphill. Because it's so affordable, it's perfect for people who want to try e-biking without spending a ton of money. However, you'll need to budget extra money for a 48V battery since the kit doesn't include one.

The biggest problem is that this kit only holds up to 220 pounds, which is pretty low compared to regular e-bikes. If you're a heavier rider or want to carry groceries and bags, you might be too heavy for this motor. It also doesn't have a screen to show your speed or battery level, and there are no built-in lights for night riding. The front wheel motor can feel strange when you steer, and it doesn't grip as well on hills as bikes with motors on the back wheel. If you need a reliable bike for daily work commutes or serious off-road riding, you should probably buy a complete e-bike instead of this conversion kit.

What We Like

  • Super powerful 1200W motor gives you lots of speed and ability to climb steep hills easily
  • Really affordable at only $150, this is one of the cheapest ways to turn your regular bike electric
  • Three different riding modes let you switch between full electric, pedal help, or normal biking
  • Safety brake levers automatically cut the motor power when you squeeze the brakes
  • Comes with all the tools and clear instructions to install it yourself without a bike shop

What Could Be Better

  • You have to buy the battery separately which will cost a lot more money on top of the $150 kit price
  • Only holds riders up to 220 pounds which is less than most e-bikes that hold 265-300+ pounds
  • No screen or display to show your speed or how much battery power you have left
  • Doesn't come with any lights so you need to buy separate lights for riding at night
  • Front wheel motor can make steering feel weird and gives less grip on hills compared to rear wheel motors
