"Our Vision Is To Build The Most Affordable And Reliable Electric Super-Bike In The World That Beats Petrol Powered Motorbikes In Their Own Field"

Visit Our Official Website MANKAMEMOTORS.COM

Introduction :

We are a Indian team of Engineers, developing what will be India's first electric Sportbike named the EP-1, The electric Sport bike will be comparable to 600-650 cc motorbikes with internal combustion engines in terms of performance, with a top speed of 250 km/h The bike will run more than 500 km on a single charge

We have built everything including the controller and other electronics and we are about to build the huge battery module, but we are out of funds as we have bootstrapped everything ourselves till now,

Please do contribute to complete the Motorcycle project, in return you will be added as a contributor on our website

even a contribution of 1000 Rs ($15) would help us a long way,

The funds will be used to,
- build 40 24V 26AH battery modules
- build and develop instrument cluster ui
- Machining costs and 3d printing costs
- get the arm computer for the Linux control board
- build the custom frame from scratch
- build body panels
Will be showcased at an Ev expo in India by the end of this year or first quarter of next year to showcase, our BMS, Main controller, and other motorcycle capabilities

We are using Milaap.org because GoFundMe or Kickstarter is not available in India

In the Video the bike is Running at no load conditions for testing at low power (2 % of total power), with

• DC input to the controller was set at 36 volts and was pulling 11 amps at full throttle on no load conditions with only the wheel spinning, the motor has the capability to run with a voltage range of 24 volts to 96 volts, max 300 amps is at full throttle and at full load giving 80-90 Nm. continuous power is rated at 12 Kw because its liquid cooled

• Output RPM to wheel set at 7500 with 2 speed active Gear box

Hello Everyone,

Your support has helped us in a great way, Our Progress till now:

1 . Our clutch-less automatic gearbox is coming around great, we have received the necessary gears and shaft, The Servo motors are yet to be delivered that we ordered a few days ago, to make the gear changes automatic and seamless, it will help us achieve great acceleration and high speed later on using very less amount of power, and using less amount of power will help us get very high range, Here is the pic of the gears yet to be made into automatic

2 . One of our Lithium ion battery module is coming along too, This is a temporary prototype in order to develop the matrix
BMS system, will update you soon

Hello Everyone,

Thank you for the support

We are currently developing a 4 speed clutch-less automatic gearbox to work in tandem with our electric motor, for torque fill, we will send you the video as soon as we complete it.

Dear Supporters,

Thank you for all the support.

The next course of action is, we will be building the software architecture to connect all the subsystems the vehicle is going to have, until we get the funds to build the battery. The list consists of :
1. A Linux based single board computer,
2. Android infotainment cluster
3. Individual wheel speed sensing
4. Rear wheel brake monitoring system (to reduce motor load while braking)
5. Fine tuning motor control

Thanks
