Application:
How do I know if the mid drive conversion kits will fit my bike ?
The Mid Drive Kits are designed to fit bikes with a 68mm (2.68 in.) or wide bottom bracket shell
and 35mm inside diameter. This encompasses the vast majority of bikes excluding some newer
high end bikes with an Integrated Bottom Bracket, and Fat tire Bikes with a 100mm wide bottom
bracket shell.
Mid-mounted electric bike advantages:
The electric bike is mounted from the overall, top-level design, people-oriented, focusing on care of the
battery (determined by accommodate design principles). To light the main structure, modeling simple, low-span
oblique bending beam (very easy to get on and off), smooth ride, high vehicle efficiency (of the same capacity battery than the hub models riding increase 5-10 km, vehicle weight to reduce 4-8 kg)
The biggest advantage of the electric bicycle is mounted: its battery, motor and gearbox are in the vicinity of the
central axis of the bicycle. So it's a good center of gravity of the dynamic balance, low center of gravity riding
unbalanced resistance, particularly without electricity as easy as riding a bicycle (built gearbox, gear ---
sprocket
combined deceleration clutch to maximize the use of standard bicycle members, human riding motor does not
turn,no magnetic block phenomenon) at 20 kilometers per hour, power glide up to 200 meters (normal riding
electric
current, 24V car ≤5A, 36V car ≤3A) .24V15Ah integration batteries, electric continuous driving can reach
more than 40 kilometers (vehicle weight of only 31 kg) 36 V car with three ordinary batteries, electric
continuous driving up to 60 kilometers, starting torque up to 25Nm, 500W.
In the home-electric vehicles. We can assist or help or strengthenriding all-electric mode. Vehicle bicycle high
rate, maintainability, wearing parts and a bike maintenance is veryconvenient. Also unique advantages can be
achieved mechanical multistage shifting, double speed (the rear axlewith an ordinary bicycle, as the installation of
mechanical transmission, which is the hub electric bicycles can notbe achieved) such that motor efficiency is
always at the highest efficiency work area. In different road conditionsand wind can shift day shift driving, avoid
large current impact.
Mechanical low gear when climbing power will begreater, can bring people climb overpass. No wonder people
call it double shift "climbing king", "double universallyday."
