The F4W Peak electric bike by Hero Eco.

The F4W Peak has a mountain bike style aluminum frame.

The cranks of the F4W Peak have a built in torque sensor that is used for the pedal assist option.  The system will sense how much power you are putting into the pedals and then provide the corresponding assist based on which level of assist you have selected (1 = low, 2 = medium, or 3 = high).  There is also the option of using the throttle while pedaling or not.

The F4W Peak comes equipped with a Shimano Alivio rear derailleur and an 8 speed cogset.

This is the 350 watt geared rear hub motor made by 8FUN (Bafang).  The 8 speed cogset provides a nice range of gear options.

The F4W Peak uses a Sony lithium ion 36V 9ah battery pack located just behind the seat tube of the frame.

The battery has an on/off switch as well as a battery level indicator.  Also visible is the lock for the battery.

The battery can be removed by unlocking it with the supplied key and rotating the battery to the side.

  1. Alan P says

    For 200 bucks more one could get 1200 watt motor, F & R BB7 disc brakes, 14 AH battery, top of the line fast charger made in Taiwan quality.
    That bike seems over priced by about a grand & I would never consider an E-Bike without disc brakes in the front .

    • Alan P. says

      The forks are weak too, those zoom forks arent good, Omega RST forks are.
      I’ll give you the Taiwan Builder then you can find the Importers who sell them in America .
      Emaxi.com.tw model MiPower.
      I’m sick of promoting the dealers here in the states I sound like a schill but I just have tried a few bikes & kits & these are really well made for peoples hard earned $.
      I’ve got 5800 miles since new 13 months ago & went 27 miles today original battery single charge 200 lbs. of me with juice left when i got home.
      I could go on, only drawback is 17 ” frames only in this model.
