    My Baja Minibike Project Begins

    Hello Everyone!!! I just got back from a two-week trip to my parcel, well last Saturday, and decided to make a final post and answer any questions regarding this project and let this thread die. I have a montra for this bike: "When you turn the throttle, it's going with-or-without you!" The...

    My Baja Minibike Project Begins

    I do have access to metal and tools but don't trust my wielding abilities. I'm good with wood and wanted to get this project on the road quickly. I don't think painting will effect the structural integrity of the wood. Wood is very viable and strong. Some airplanes are made entirely out of wood...

    My Baja Minibike Project Begins

    Hello everyone! This project is finally coming to an end! I got the dashboard built, wired-up the SureFun data logger and got it working and got a Cell Logger 8S wired up. My Pyramid power supply died, but Amazon replaced it within days!!! I still have lots of minor things to do but most is...

    My Baja Minibike Project Begins

    Hello All, Another busy day. Everything came together and is finally making sense. Friday (May 7, 2010) I put the controller and associated parts on a 'real' platform instead of what I had. With the final design, I no longer need to remove the batteries to charge them. Sometimes it's the...

    I think I'm going to answer my own question posted above. "Never overlook the obvious" The 'mOhm' in the CA manual stands for Milli Ohm, not Mega Ohm. Since Volts = Amps x Ohms, and my shunt is 50 mv at 100 amps, I can calculate the ohms, which should be 0.500 milli ohms in High Range mode of...

    My Baja Minibike Project Begins

    Sorry for the lack of pictures, but I just finished my trials, the sun is setting and I'm totally confused. How accurate is the Cycle Analysis (CA)? According to it, I'll get about 47.5 miles on a charge using eight 40 amp batteries. That does not seem possible since most posts I've seen are...

    Huston, the spacecraft has cleared the tower... What a busy day today! I finalized the mounting brackets and ended up completing the mini bike... well about 80% done. I took it for a ride about 2 am my time!!! WHAT A BLAST!!!!! I was worried about the wood braces but they didn't even flinch...

    My Baja Minibike Project Begins

    Hello All. This is an update of the project so far... Pictures will come later. The only wielders I found work Monday to Friday 8:00 am to 5:00 pm and are far from me. So I decided to build the battery and motor housing myself out of wood since I don't know how to wield or have the equipment...

    My Baja Minibike Project Begins

    Hello Everyone! All the parts for my project finally came in last Friday (04/16/2010). Oddly enough the first part I ordered was the last to arrive which was a sprocket for the motor. I have two 3.2v 40 ah batteries on back-order but I have enough to build a 24 volt system for testing. The...

    My Baja Minibike Project Begins

    Good stuff FeralDog. Locking the front forks is a great idea! I don't want to give the wrong impression here with regards to the use of this bike. My parcel is very flat and not rocky at all. I doubt there are any slopes greater than 10 degrees and no rocks that can't be avoided. Very mild...

    My Baja Minibike Project Begins

    Hello Wasp! My first criteria for the frame were the fattest tires I could find. I've been riding motorcycles forever and found when riding in snow, mud or sand that is the way to go. The next criteria is a low seat. It's nice to be able to stabilize yourself with your legs without straddling...

    My Baja Minibike Project Begins

    GMTA. I've been keeping my eye out for a Rokon but If I were to use it, I'd keep the front/rear drive-train enact and replace the 15hp motor with an ME-709 or something similar with 15 hp nominal. They have all the bugs worked out on synchronizing the wheels already and why 'reinvent the wheel'...

    My Baja Minibike Project Begins

    Hello FeralDog! Good advice all around and much appreciated! I guess it's prudent to disclose the purpose of this project. I have a 640 acre parcel in a remote location at an altitude of 6500 feet off the grid. Since I live at 1500 feet, walking around the parcel wears me out. There are no...

    My Baja Minibike Project Begins

    Thanks for the reply mdd0127! As luck would have it, I'm only going to receive 11 cells (one back-ordered) so I'm going to initially build a 24 volt system. That comes to about 28 pounds for the batteries. With the motor, controller and batteries, I'll actually be under the weight of the stuff...

    FLYING with electricity

    Yea Lock, that's the ticket! Nice to see the propeller assembly can be retracted because a stalled blade acts like an air brake.

    FLYING with electricity

    I'll chime in since I have a glider and single engine land rating. Probably the best application for EV in the air would be in a powered glider. Gliders really don't care about weight so much. In fact, some of the hi performance gliders use weights (water) to increase their distance to find the...

    My Baja Minibike Project Begins

    Hello everyone, I'm a long-time lurker and have finally decided to build something small that I can use to roam a parcel I have in a remote location. It has some steep hills to traverse so I opted for a system with higher current. My electronics knowledge is extensive, but not with high-amp DC...
