There are a lot of people with DIY cargo bikes in my city like this:


and there aree lot of places where bicycle is the ultimate conmuter cargo machine :








Anyway, your fuel consumption is a very good result with a petrol engine.

Great thread guys. Much to read and much to learn...

update: my car is now (lead acid free) my new battery is a lifepo4 20ah battery in parallel with a 108farad 16v capacitor ( 6 650farad 2.7v capacitor in series) it weight about 12 lbs.






the capacitor are there for the cranking amps because my lifepo4 battery can't start the car alone but the capacitor alone can do it . another use of the capacitor will be when I have to reinstall my belt (I dont want to charge the lifeo4 battery with my alt).

I found 2 li ion drill batteries and I thought: how can I use the power of those batteries to go further without belt. the solution, use the electricity of those battery to power my electric water pump. I made a switch that chose the source of the ewp (main battery or drill battery)
the battery is made of 20 3.7v 1.4ah li ion battery (5 packs of 4 battery in series in parrallel) that give a 7ah 14.4v battery

update: I decided to use my ewp to circulate the coolant when I use my block heater. I made a circuit that send a 12v output 1 minute every 15minute (my ewp controller begin with 30sec off 10 sec on... so 1 minute on= 10 sec on) the circuit take its power from a 12v power supply pluged in the timer where I plug my block heater

I just saw your garage and :
do you have a picture of your Jones Glasspack muffler
and how will you remove 56lb on the driveline ?
