How this e-bike scores for different riding styles

High Performance
70/100

The 48V 1000W motor option delivers strong power and 31 mph top speed, appealing to performance seekers. However, small 20-inch wheels limit high-speed stability and control.

Recreational Leisure
55/100

The kit can convert a casual bike for leisurely rides with pedal assist and throttle, but lacks comfort features and requires technical installation that casual riders may find challenging.

Off-Road Adventure
50/100

The 1000W motor option provides adequate power for trails, but the 20-inch wheel size and lack of suspension make it poorly suited for serious off-road terrain and rough trails.

Daily Commuting
45/100

This is a conversion kit, not a complete bike, which makes it impractical for daily commuting needs. It lacks essential commuter features like integrated lights and requires DIY installation expertise.

Compact & Portable
35/100

While the 20-inch wheel size is compact, this is a conversion kit that doesn't fold and adds weight to existing bikes, limiting true portability benefits.

Cargo & Utility
30/100

As a conversion kit with no structural reinforcements or cargo-specific features, it's unsuitable for heavy hauling. No data on weight capacity or cargo accessories.

Our Verdict

This conversion kit is a budget-friendly way to turn your regular bike into an electric one, but it's really more of a DIY project than a ready-to-ride solution. At $118, the price looks amazing, but remember you still need to buy a battery separately, which could cost another $200-400 depending on what you choose. The 1000W motor option is pretty powerful and can get you going up to 31 mph, which is faster than most regular electric bikes. It comes with an LCD screen to see your speed and battery level, plus you get both a throttle and pedal assist, so you can ride it like a motorcycle or get a boost while pedaling.

This kit works best for someone who already has a 20-inch bike they love and wants to add electric power to it. It's great for people who are handy with tools and enjoy working on their bikes. If you like tinkering and want to save money by doing it yourself, this could be a fun project. The small 20-inch wheels mean this is better for short trips around town rather than long rides. It's good for quick errands, short commutes, or just zipping around your neighborhood. The powerful motor makes hills easier and lets you get places faster without breaking a sweat.

However, this kit has some serious limitations to consider. The biggest issue is that it doesn't come with a battery, so the real cost is much higher than $118. The small wheels and no suspension mean bumpy roads will feel rough, and riding at high speeds might feel unstable. It's missing safety features like built-in lights, and it doesn't have UL certification, which means there's no official safety testing. If you're not comfortable installing bike parts yourself, you'll need to pay someone to do it, adding more cost. People who want a complete, ready-to-ride electric bike, or those who aren't confident with bike repairs, should look at complete electric bikes instead.

What We Like

  • Very affordable at just $118, making it one of the cheapest ways to electrify your existing bike
  • Strong 1000W motor option delivers good power and speeds up to 31 mph for those who want performance
  • Works with both front and rear wheels, and fits V-brakes or disc brakes so it's flexible for different bikes
  • Comes with LCD display, throttle, and pedal assist - all the basic electric bike features you need
  • Already includes the wheel rim and motor pre-assembled, so you just need to move your tire over and install it

What Could Be Better

  • Does not include a battery, so you'll need to buy one separately which adds significant cost to the total price
  • Small 20-inch wheels make for a less stable ride, especially at higher speeds or on bumpy roads
  • No suspension means every bump and crack in the road goes straight to your body on rough surfaces
  • Missing important safety features like lights and no UL certification to verify it meets safety standards
  • Requires technical skills to install correctly - not ideal if you're not comfortable working on bikes yourself
