This bike is not suitable for getting off
the line quickly. Its power and efficiency
is noticeable and appreciable mainly while
riding at least 30 kph
Accelerationfor people that try it first time it is
surprising and they like it very much
Range125 Miles (201 Kilometers)
Using full power in a bit hilly area could
be 50-60 km. Usually I get over 100km
easily. On pretty straight road (low total
elevation) I travelled 150km while drained
15Ah with average speed 38kph.

Conversion Timeless than one week
Conversion Cost$1000 - $1500
Additional Features3mm motorcycle spokes, "speed" handlebars, pedal gear 48 plus
rear gear 11 = I can still pedal while going 50 - 60 kph
super price for kilometer, better for health because I am still
pedaling while riding, its fun to pass other bicycle riders
(they wont hear anything until you pass them). The best thing
is to pass those with super expensive carbon road bicycles,
dresses, bicycle shorts etc... From the back or front side of
the bike it is not noticeable that it is electric bike. Some
people do not recognize it even while standing right next to it
(they think I have kinda toolbox instead of battery)
