The bike in the early days
Here you can see the power point I installed on out the outside wall of my place (above)
After programmable battery level monitor
The 3.5″ K-32 tyres were my first choice to replace the 3.0″ tyres that came with the bike
New shocks. The ride quality got much better after I replaced the substandard ones that came with it
Some bling to celebrate the 72V upgrade
After the 72V SLA upgrade – the underseat compartment
I replaced the headlight and sidelights with LED modules – much brighter and more efficient
The 24s2p LiFePO4 Lithium pack build
The BMS, built from scratch with a Goodrum-Fechter board
A BMSBattery EMC-900 charger charges the pack at 9 Amps – total recharge time 2 hours 50 minutes from ‘flat’
After the LiFePO4 Lithium pack upgrade
I used three CellLogs to give me a battery pack monitor for the Lithium pack
The torque arms that came with the bike (right) were too fragile, so I designed a more sturdy, heavy-duty torque arm
Here’s the new torque-arm in situ
Switched from 3.5″ K-62 to 4.22″ equivalent ‘Big Bopper‘ tyres
Fitting the bigger tyres and adjusting the mud-guard
After respray and rebuild with 1500W motor, 16-FET controller, lengthened centre-stand legs and Big Bopper tyres
I built this custom, copper heatsink to mount the controller on
After over 2 years faithful service, my BMSBattery EMC-900 charger finally blew up, so I upgraded to the more powerful EMC-1200 above. This is now running 13.6A, giving a full recharge in about 2 hours, as compared to the 2 hours 50 minutes needed with the old charger running at 9A
