Hey all,
I thought I might share a project of mine.I've always wanted to have a motorbike but since i'm not too confident on the road I thought I would explore the options of converting a bicycle, moreso in particular a Chopper Style one.
I ended up buying a Flight Dragster bike a few days ago and i've started working on some 3d models and some calculations on how to mount the batteries, speed controller and other electronics.
Vehicle Specifications:
Flight Dragster Bike
24" Front Wheel
20x4" Fat Rear Tyre
I have gone for a front hub kit since I am unable to find one to suit the very fat 4" wide tyre at the back.
The idea would be to build a charging system that would be able to charge each battery pack seperately which would keep the packs in good nick as well as allowing me to fully charge the whole pack in about 1 hour or so. I am still working out a plug system in way that each battery when charging would be isolated from the rest without having to disconnect the series bridges (maybe I could use a number of switches to isolate the series).
The bike will have a H3 Fog Light on the front for those days/nights I might need a bit more light. It will be powered from an auxiliary 12v battery which will still need to be designed. The bulb will be replaced using a h3 LED light which has 1/6th of the power usage.
Motor Choice
I will be using a 36v 350w 24" Front Wheel eBay kit as the power source. I was quite specific in wanting the twist throttle which will be great.
Battery Choice
I know they aren't the most popular but I got a decent price for a set of 3 12Vx 12ah SLA Batteries for around $90aus which was good enough to try out. Long term LifePO4 will be good but cash is a bit shorter than expected at the moment.
Creature Comforts
- GPS/Music Supplied by my Wildfire G8 Phone on a handlebar mounting kit
- I am working on a Custom Trailer which will be used to store food, supplies and the possibility of extra batteries depending on the distances travelled. I'm tempted to chuck in 3 small 55ah 12v car batteries in the back and do some long distance rides lmao. Weight would be an issue haha
- eBay Alloy Pedals
Wearing the style
I seem to like to look the part when cruising around on an old dragster/chopper so i've made a few small purchases off eBay which include some oldschool leather/metal riding goggles, a brown leather jacket and a white scarf hahaha
As you can see I like to have a joke around, and what better way than to have a fun environmentally friendly bike.
Here are a few of the bike.
I used 3D so I can plan everything out easier than I can draw.
My skills aren't the best in 3d but they are functional hehe
Here is a 3d render of how the batteries may be positioned in a saddle pack
Any comments would be more than welcome
