Frame type: 4-bar vertical spring aluminum dual suspension frame
Frame material: Aluminum for light weight and durability
Suspension fork: RST Capa-T6; coil/MCU spring, non-adjustable 75mm
Rear suspension: Adjustable coil
MotorCrystalyte model 5305 Brute 5000 serie Brushless DC
This motor can take 9KW and deliver a torque of 200N.m at dead stop and 120N.m at 40kph.

It's a brushless using hall effect.
ControllerCrystalyte 100V 90A for brushless motor
this is a original 72V 35A Start immediate that i moded with 12 IRFB4110 Mosfet. I also replaced the large capacitor inside with lower ESR and larger capacity
Batteries432 Sony 18650V (known as Konion).used in Makita, Bionx an, 3.75 Volt, Lithium-Ion
2.21 Kilowatt-hour LiMnO2
I built this pack myself with engineering knowledge for thermal management and safety protections.
I used many used 18V 3Ah LXT power tools battery pack of Makita.
These cells are 1600mAh each and are mounted in 24s 18p groups.
The total pack give 100.8V fully charged and 24Ah.
can take 10C discharge

no need equalizing!!
System Voltage101 Volts
Charger Doctorbass DIY 1.0kW charger/Balancer
I take 2h10 for full charge!

I built the 20A rate multi charger.
it is made of 12 DC-DC Artesyn converter that are adjusted to 4.2V and 20A current limit.. all DC-DC are powered by a Meanwell 48V 32A PFC power supply.
DC/DC ConverterVicor
I used some DC-DC to lower the voltage to 12V to supply accessory like headlight, rear light and navigation computer and GPS.
Instrumentation-Cycle analyst V2.0 ebike computer
-4 Voltage meter
-Motor temp meter
-Accelerometer (beltronic racing instrument)
Top Speed47 MPH (75 KPH)
I measured that on flat no wind with my GPS and the battery was fully charged to 100.9V.
Acceleration0-20kph 0.53sec!!
0-40kph 2.71sec!!
0-60kph 6.9sec

0-100m 8.71sec
tested with 40 pounds of battery and 6.6kW max

Range153 Miles (246 Kilometers)
At 40kph on normal road I get 200km with one full charge and
Watt Hours/Mile21 Wh/Mile
at 40kph it draw 21Wh/mile
EV Miles
Current:5,412 Miles (8,707 Kilometers)
Seating Capacity1 adult
Curb Weight129 Pounds (58 Kilograms)
Fully loaded this bike is heavy but the frame can take it easily.

The acceleration is still amazing!
Tiresnormal 2.1 x 26 and 24inches
Conversion TimeI stopped counting
Conversion Cost2500$
Additional FeaturesThis project is the next one after my first trek 960 ebike.

The goal was to get a lower center of gravity and more room for the battery.

And also having great suspension!!
