Trek 500w Ebike Build & Top Speed Test Ride!

Kirbebike's 500W e-bike conversion kit, in riding it doesn't deliver the super exciting riding thrill that a high-speed e-bike does. This is a 500-watt hub motor, and if you compare this to the rear wheel, you will see that it is gearless. It's smaller, lighter, not as chunky, and still fast.
The 36-volt battery will be a little smaller than a 48-volt e-bike, but with double the range, you can safely take the bike out for a full day of fun. At 10 miles per hour, you'll be able to better enjoy the scenery along the ride.

Smaller Size, Longer Range, And Shorter Charging Time

The KirbEbike e-bike kit is combined with a new 48v12-17.5Ah lithium battery that is smaller but more versatile. The battery effectively increases the range, stability, and safety of the bike. The range is 30-50km on a single charge and the battery will retain 80% of its capacity after 1000 charges. The life span of the lithium battery pack is 3 years.

Frequently Asked Questions

Mileage rates are based on a 170-pound rider riding a 30-pound bike on a flat paved surface, with no wind, using the motor, and no pedals. Your mileage may vary, but most people get more miles than advertised. For best mileage, we recommend pedaling with the motor on.

Most of our electric bike conversion kits can reach a top speed of 25-30 Km/h, but the 1000W model can reach speeds of 45-50 Km/h. These speed limits are primarily set by the laws governing bicycles. Requirements for bicycles with a top speed of more than 25 km/h may require additional permits and are subject to different traffic regulations.

Great product

I have had this motor installed for about 1 month and have had no issues. Easy install. Package came within the time stated. I did get the brake handles sent separately but I didn't need them right away. Motor and battery work great so far after almost 200 miles. Have fun it's way better than buying an ebike with less power. Just make sure your bike is ready and can handle the power. I had to tweak a few things to adjust.

Great communication

I ordered the kirb with a 52v 21ah. Very powerful combination. I recommend ordering one size bigger than you think you need. The last 40 percent of the battery causes a slight loss of strength in the motor. I am handy so it was a 2 hour job for me to install. The seller has great communication and shipped quickly.

5.0 out of 5 stars Great kit, made our bikes a completely different kind of fun! Thanks Krib Store!

The Kirbebike kit is great, lots of power, we get 16 miles on our 52v 17.5AH battery mostly riding at full throttle. The kit is so good that we have bought 3 sets from the KIRB store so far.

The biggest thing to worry about if converting the bike is the bottom bracket clearance. Also, even with mechanical brakes, brake sensors for hydraulic brakes are almost always more valuable than brake levers, just add the sensors to your original brake levers.
