HI ES Non Hub Big Boys!
I lurked on the forum a few years ago and was inspired to get a Greenspeed Trike by some of the projects going on then! I fell in love with the trike and never got round to electrifying it! Have dropped on here infrequently over the last few years and have always been blown away by what was going on!
BTW absolutely love this forum and the amazing stuff that goes on! Such important innovation space! I can see the old masters haven't laid down their weapons and are still cutting away at the cutting edge! MINDBLOWING Recumpence, Aussie Jester, Thud, Ypedal thanks for leading the world electric Endless!!!
I'm still scared about this - really don't want to screw up my machine and really wanna know if you guys think it's going to be feasible and worth attempting by someone like be!
I live in Central Australia and can ride my trike to work everyday - is 10.8kms but it regularly gets up to 45C (113F)! The Greenspeed GT3 series 1 has 3 X 16in wheels for lower cornering and strength and is a blast to ride! Don't wanna overpower it or spoil it! Make sure I've researched things properly first!
PROJECT PROPOSAL:
Electric Assist, Light as possible, Low Power, High efficiency, reliable, easy enough for a total noob to put together (hopefully), single speed, 24V or ~6S LiPo (this makes it easier to set up a solar charger), Shumaker drive with small Astro if I can get a 16in wheel made up with a RHS freewheel. So much space on the GT3 frame behind the seat should be really straight forward and would look awesome!
I spin out at around 22MPH with the way it's geared at the moment. Would love a top speed of ~35MPH and just a little electric assist so I can still ride to work in the stinking heat!
Not sure if there is any Greenspeed related experience doing this kind of thing on the forum too?
1st Question!
I don't make the skills or knowledge how to fit a RHS freewheel on a wheel!
Are any members here willing/able to build a 16in (349mm) rear wheel with a freewheeling LHS cog and a 9 speed Capreo cassette? Would happily pay to have one made up with the 9 speed cassette on the other side anybody have the time/skills inclination?
The 16in Greenspeed wheels don't come with a Brake Adapter. (I'll post pics soon)!
The trike has a Shimano Capreo 9 speed cassette with a 9 tooth cog on the right hand side

Apparently Greenspeed modified them to their own needs:

2nd Q!
The wheels are 349mm diameter.
Just going over the motor numbers - 6S or 7S max with 16in wheels means I need a fairly high kV motor and aim for a total reduction of 12.5-15. I was looking at a 3 turn Astro 3210 or 4 turn Astro 3205 to get to 30MPH? Wanna carry ~20000mah for a 40-50KM range with conservative throttle use and pedalling using 20Wh/km? Does this sound right feasible? Will the motors be in danger if they are only spinning at ~3000RPM at 10MPH?
I wanna find out how a light efficient RC setup handles the harsh Australian climate and dust?
Here's what I think I should be getting -pretty straight forward (I think!) but let me know what I've missed (nothing ordered yet):
Shumaker V4 Drive
Astro 3205 or 3210.
RC Servo throttle thingy
HPV110 or HV160?
4P6S LiPo with fairly insulating case to keep them out of the sun and heat!
Batt charger
Chain
16in Wheel made up with Special freewheel
RC Cycle Analyst with current limiting so I can turn the current right down and temp monitor the motor.
(have some electronics knowledge and can wire stuff and connect andersons but the metallic freewheel fab stuff is well beyond me guys!!)
Cheers all thanks for reading my longwinded post!
