I BUILT my first UK LEGAL 250w Ebike to see HOW FAST IT CAN GO!!!

The andy kirby 250 watt kit that's with a 48 volt battery,i've actually fitted for the first time ever pedal assist.as well as a half grip throttle combined .i kind of like it i think on the long journey you haven’t got bother.touching the throttle it's actually quite quite good.You know it's a good all-rounder you've not got a massive heavy motor wheel.you can actually when the battery's flat you can ride this as a normal.mounting bike and apart from the weight of the battery. Used to this pedal assist it's very much on or off whereas a throttle you've got a lot more control over how much.

Smaller Size, Longer Range, And Shorter Charging Time

The KirbEbike e-bike kit is combined with a new 36v13Ah lithium battery that is smaller but more versatile. The battery effectively increases the range, stability, and safety of the bike. The range is 35-45km 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

Our kit is suitable for most bicycles, but please view the below details for reference.

Firstly, a 36v 250w front motor system is installed on the front fork instead of the bicycle's front wheel. And its dropouts are 100mm. So please confirm your front fork dropouts is 100mm. Please click Dropouts and view the video of the Dropouts measurement.

Secondly, please choose the wheel size, we have 20" 26" 27.5" 28" 29" 700C wheels. If you are not sure which wheel size fits your bicycle, please click the wheel size to check how to confirm your bicycle wheel size.

At the last, please choose the battery you like. Here is a short video about the installation of the downtube battery and rear rack battery. 

Please contact us at support@kirbebike.com if you have more questions.

How Far Can I Go (Battery Range)?

36V 13Ah battery has 30-40 miles of range
36V 16Ah battery has 38-45 miles of range
36V 18Ah battery has 42-50 miles of range
48V 13Ah battery has 40-50 miles of range
48V 16Ah battery has 50-60 miles of range
48V 19.2Ah battery has 60-70 miles of range
48V 21Ah battery has 65-75 miles of range

All figures are in pure electric mode, the actual mileage will be farther if there is pedal assist.

LG cells are better in product quality and stability, so the price is more expensive.
