Hi Guys,
So I have been asked to find out what would be the best upgrades for the trike below ( or very similar)..
It has a 1500w motor ( Chinese Watts :wink: ) and 60v 20Ah Battery..
In it's current state, it does around 45kph ( again, Chinese kph lol ) using GPS around 27-29mph. In truth speed is not the problem or a big factor.
Lets say I have £500 to spend.
Need to have :
A multiposition switch to limit speed 5mph/10mph but able to climb relatively steep inclines so plenty of torque. The current 3 speed switch seems to limit power rather than speed ( thats how it seems )
"Normal speed" upto 25ish
The main thing is and I have had some ( LOADS ! ) help, but in truth, was not successful or should I say, not good enough for what I was needed.. It's a slow/soft start the main thing, these things and am sure it's been discussed many times, the leap away when you turn the throttle ( that is eventually as seem to turn the throttle a long way till things start to happen ). This needs to be soft and silky smooth These guys Range Rovers that have been converted to EV using Tesla guts, they want silky smooth on these trikes as well ..
To me, I would imaging all this can be done with a suitable programmable speed controller, which is where I am struggling, but I have no doubt you guys will just point me at the right place, ideally if it could handle upto 2000w that would be perfect
Other upgrades I have on the list:
The list I currently do seems huge when noted down, but it's less than 4 hours work to be honest, I just can't think of anything else that needs to be done to make these things better, please if you can think of something let me know
P.S. I'm not footing the bill for this, just making them "right" with a healthy budget.
And yes, they are landed for less than the budget I have for the speed controller side of things, but hey, they are well aware of this and don't care, the joys of having money to burn I guess !

Other upgrades I have on the list:
- The brake lines !!! SHOCKING They manufacturers seem to have a one size fits all, which means brake lines are chafing on various parts, so I'll be changing them out for Stainless Braided hose of the correct lengths and they will be appropriately routed and fixed.
- All fasteners, wow, obviously they are using the cheapest possible, so they are getting changed for Stainless rather than Zinc coated Chinesium toffee steel.
- On the frame, I have noticed on the few I have have seen and repaired for people that there are a few places of weakness and suffer with stress fractures, my repair have been to please and reinforce 2 parts of the frame which in fairness only takes around 30mins including the welding. Which again has shown up the quality of the steel used, just plain nasty...
- The handlebar headstock ( not sure what it's called in this world ), the current thing, is this horrible cast ally thing, where the screws/both which clamp just rip threads out and the internal serrations just round over as the metal is so soft, I have redesigned this part and it is now made out of a billet alloy ( mate owns engineering company so selected it for me ), uses some funky wire erosion machine to make them for me, well cool to watch !
- Currently the only wiring that is not touched is that from the motor, all the other wiring is "adjusted" as appropriate so you don't have a birds nest hidden away, but a nice tidy loom, with better connectors.
- Lastly, another small change to the frame, on the left side is a mount for a side stand which is used when the frame is used for a single rear wheel, this ankle/calf ripping device is removed.
