Vehicle	2010 Electric Trike Rather than taking an existing second hand motorcycle and fashioning it into a trike, I opted to take the more laborious route and build it from the ground up.
Motor	Kostov R20-32079 - 11 inch - 250v Series Wound DC Motor is capable of being bi-wired to allow series / parallel switching.
Drivetrain	Direct drive - 31 spline 9" diff Gleason: 3.1:1 low drag gear set (back cut to lighten reciprocal mass) Strange Engineering: Aluminum case, forged pinion support. UPDATED - changed to a Yukon 10 bolt case with bolt through centre. Forged pinion support changed to a custom one, with built in torque tube. Eaton: Tru-Trac (worm style) centre. Strange Engineering: Forged yoke, custom 30" flange to flange housing, SST axles with 5 lightening holes. Self: Axle flange plates with added material to support brake caliper brackets, spacers, brake caliper brackets. Brembo: 5 stud (114.3mm / 4.5") Nissan 200sx aftermarket rear rotors Wilwood: Calipers front and rear.
Controller	Evnetics Soliton1 Will handle over 300v and up to 1400A (racing warranty). I am leaving mine at the factory set 1000A.
Batteries	160, 3.65 Volt, Lithium-Ion 80S2P - Investigating A123 batteries at the moment.
System Voltage	292 Volts
Charger	Elcon 2kW 292v - 8A TCcharger (previously Elcon) 80 Series * 3.65v with CAN Bus option
Heater	Leather jacket. Cooling: open jacket.
Instrumentation	Digital display.
Top Speed	125 MPH (201 KPH) Unknown at present guestimate around 200 kph.
Acceleration	Expecting 60ft times and possibly 330ft times to be much quicker than the ZX-10R, after that the Kawasaki will probably out accelerate it.
Range	Hoping for 100+ klms (62.7 miles). More likely to be around 50-60 klms if I go with a less Ah pack.
Seating Capacity	One with possibly a second removable seat.
Curb Weight	992 Pounds (450 Kilograms) Regulations state it must be less than 450kgs
Tires	Rear: 17" x 8" Centerline wheels with 235/45- 17 tyres. Front:17" x 3.5" custom made Dragway wheel with 140/80-17 Metzeler ME880 tyre.
Conversion Time	Your guess is as good as mine at this point.
Conversion Cost	Estimate $35k+
Additional Features	Planning on using a home built girder front. Frame will be made of 4130 Chrome-Moly. EMS: Wicom 5.7" LCD screen Central Control Module 5 Data Control Modules (16 cells each) 500A current sensor
Looking forward to taking it for a spin. 16 Aug 2010: New "Rev" series Centerline 17" x 8", 3.5" backspace wheels are now here. Kostov motor has been delayed but should be here in a couple of weeks. Decided to use Wilwood calipers instead of reconditioning factory units on rear. 14 Sept 2010: 17" Rotoforged front wheel has now been manufactured to design. 235/45-17 tyres purchased and ready to go on once the Centerlines are polished to an acceptable finish. 6 Oct 2010: Motor turned up today, starting to look a little more like a trike now. 25 Oct 2010: Finally got my Russell brake rotors and mounting bolts a month late. Ordered Wicom EMS and TC Charger (Elcon) from China. Ordered TCB's from K & G Cycles USA. Still waiting on front guard. 15 Nov 2010: Wilwood / Harley front calipers arrived. 23 Nov 2010: Wicom EMS arrived. 26 Nov 2010: TCcharger battery charger turned up today. Finished polishing the Centerline wheels to an acceptable finish and mounted tyres. 6 Dec 2010: 4 TCBs (Traction Controlled Braking) arrived. Will be using them on all 4 calipers (2 front, 2 rear) to help pass ADR braking tests. 4 Jan 2011: Front guard is now here and I get my first real look at what the front wheel is going to look like. 5 Feb 2011: Rear Wilwood calipers arrived. Will need to make some new rear brake caliper brackets, as old ones were designed for the Nissan calipers. 16 Feb 2011 Update: Designing a rear suspension that allows full movement and functionality without taking up excess space has been quite challenging. Currently working on trying to offset some of the unsprung weight by pivoting the motor further back towards the diff. Final design is close, and will hopefully be able to move into fabrication soon. Design is loosely based around a single heim / rose joint and the top front, and a Watts link on the rear. 17 Nov 2013 Update Been quite some time since my last update. Recently got motivated enough to start working on the trike again. Been designing the motor to diff coupling and purchased a huge solid chunk of aluminum to create a torque tube. Need to finish the coupling first, then will move on to making the torque tube. 7 Mar 2016 Time has passed and I haven't been in the position to move forward in quite some time, but three months ago I started getting some work done on the torque tube. After much chasing it has just been finished and ready for assembly. 2 Sept 2017 Finally got around to taking the new 10 pinion bolt diff centre and torque tube / pinion support to be assembled. Should be ready next week if there is no problems with the manufactured torque tube / pinion support. June 2021 Still waiting to get some shed space and spare money to finish the project. I haven't given up.
