Building the Electric Death Trike took a span of a little over a year. The KMX Typhoon trike was picked up for a measly $700, a craigslist special. Although I have seen these trikes for as low as $500 on craigslist.

The first night I brought the trike home, I installed a Bafang BBS02 and a 48V battery onto it. From there the first version of the Death Trike was born, in its slowest incarnation.

The BBS02 wasn’t particularly powerful, torque was passable in the lower gears and eventually the trike would hit 30mph top speed. However, the trike did struggle with steep hills, often just crawling up steep grades.  Shifting the trike constantly would become old especially when riding it on the street. Additionally, the BBS02 would become hot on extended rides, the small motor could not handle the extra weight and load of the Trike.

Death Trike V2 discarded the BBS02 and replaced it with the potent Cyclone 3000W motor, the bike now had dramatically more power compared to the BBS02.

The Cyclone is a bigger and heavier motor, with significantly beefed up internals. Torque, acceleration, and hill climbing abilities have significantly improved compared to the BBS02 but it was significantly louder. Moving up to 72V, the motor ran at a higher RPM so I can could get more use out of each gear. Shifting wasn’t as bad, and it was actually fun as It felt like a Formula-E car with fast and crisp shifting.

Due to the increase power and the long chain line, it caused all sorts of problems including snapping the deraileur hanger, chain tubes,  chain and etc. This has left me stranded on several occasions and I’ve decided to go hub motor to alleviate the problems associated with mid drives.

This is the Death Trike in its current rendition, running a 72V 16AH battery with a MXUS V3 3K Turbo and Sabvoton 72V150A controller. Power has gone up significantly, now the Trike is putting out 11Kw compared to the 3Kw with the Cyclone motor. Top speed is now a little over 50mph, and the Trike gets there in only a few seconds.  The Trike runs smoothly and silently due to the Sinewave Sabvoton Controller. Also, the Trike has forward and reverse.

Front 14
Front 14″ NR77 Moped Tires

Front Wheel Setup has also been upgraded from the stock 16″ Bicycle Tires and Wheels to 14″ Dirt Bike Rims and 14″ x 2.75 IRC NR77 Moped Racing Tires.

Rear Tire has been upgraded from the Shinko 16″ x 2.25 to Pirelli 16″ x 2.75. Rim is a 20″ XL Trippin BMX Rim.

The Sabvoton Controller is completely maxed out at 150A, with regen capabilities for rear braking. With a 74V battery, output was 150A from the battery and 350A to the motor.

The MXUS motor would run a little warm especially at higher power levels, a QS V3 205 motor would take care of any heat issues. Power is more than adequate however, a front steering stabilizer would take care of the front end wobble.

Yes, the trike is driftable.

Thank you for reading this article, I did took the time and effort to write it so hopefully you the reader learned a bit about building the Death Trike, as I did enjoyed riding it.
