Hello all,
I am new here and this is my project. I am taking two Yamaha MX Bike Chassis, and making a 2 person side by side 4 wheel ATV out of them, Electric power, of course. I have obtained the bikes already and have found a place to build it,as I can't do it at home per HOA. I have a 48 volt golf cart motor and controller that I plan to start with, and upgrade the motor after the bugs are worked out on the buggy. I will probably start with FLA batteries, (4) 12volt, to get the buggy driving quickly, and go to Lithium later (Chevy Volts so far). My goal is: It has to be able to fit into the back of our double cab 2013 Toyota Tundra truck with the tailgate up while we pull our camp trailer, it has to have good off road suspension as we explore old mine roads, it has to be light, I want 40+ mph speed so we can use it on local public roads, and I want at least 50 mile range, and...I'd like to be able to put a small 2000 watt generator on the machine to partially recharge while we are out in the back woods, but that is just "Cake Icing" and may not even be feasible, ( weight of onboard charger and gen. might be better used with just more batteries). Right now my main sticking points are, a Differential to split the power from a motor to the 2 chain drives on the bike swing-arms, and the best motor to go to when I upgrade. I welcome all constructive comments, and any others too! The added bottom picture is my early Sketch-Up drawing of the bike-buggy.
