Charger 4К electric bicycle series are based on modular locally developed laser-cut steel frame. We put lots of effort to make really powerful and reliable battery using latest large capacity lithium NMC cells from electric car industry.
Charger 4K — powerful hub motor electric bicycle
This electric bike gives it's ovner maximum freedom. It can be comfortable long range city commuter as well as recreational offroad explorer. You can trensport the bike via railway or a car thanks to it's relatively low weight (around 45 kg).
The battery
Charger's battery is made of branded Li-NMC cells capable of high power output and long life cycle. Battery's expected lifetime range is more then 50 000 km.
Range
Bike range for 1.3 kWh battery, depended on speed:
Up to 130 km on 25 km/h, with pedal assist
Up to 65 km on 45 km/h, throttle only
Up to 40 km on 60 km/h, throttle only
Battery tech specs
Energy stored: 1296 Wh
Nominal voltage: 48v
Capacity: 27Ah
Chemistry: Li-NMC
Lifetime: 80% capacity after 1000 cycles
Hub motor is low maintaince motor
The motor
Motor type: direct drive hub motor
Rated power: 3kW (check you local regulations)
Peak power: 4-6kW, depending on config
Max speed: up to 60 km/h
Regenerative breaking (recuperation) — charges battery while breaking and saves break pads.

Controls
You can directly control motor power with a standard throttle.
There is 3-position switch for power levels, adjustable via APP.
Regenerative breaking turns on through break leaver sensors, which also cuts off motor power.
There is cruise control function.
Display
Battery charge level, speedometer, odometer are displayed on your mobile phone via special APP. Using this app, you can also adjust other controller settings, such as regen strength, soft start, 3-position switch and more.
Pedals
Why would you need pedals with 3000w motor? Here is why:
• Using pedals, you can comfortably extend your range up to 4 tumes.
• If you run out of charge, you don't have to walk home or call bike transporter. Just pedal as normal bicycle.
• You are cyclist and can use bicycle paths and other infrastructure, while pedaling, according with your local regulations.
Lots of energy stored inside the bike frame!
The frame
Charger4K is assembled using modular, locally developed high presicion laser-cut steel frame.
Dual suspension with adjustable rear shocks mount, using high quality and lightweight bicycle parts. DNM rear shocks with preload-rebound adjustments, front fork with preload-rebound adjustments.
