    All about BALANCE

    I would suggest a tadpole trike with a seat height as low as you are comfortable with, (an office chair with arms works best for me, if you are powered extra weight is not a problem) easy to get in and out of, widest wheel base you can get away with, every one that has a Works-man type delta...

    Bafang 8FUN + External Controller?

    By hearsay I heard of a company (retail sales) that is/was considering using a external controller on the 750watt Bafang motor, but they have had some returns on the standard motor battery system, owners using the unit under full power (off road hills?) as much as they could, have destroyed the...

    Best Volt meter

    Analog in volt meters, or clocks, if all you need is a indication , reading a analog clock takes a split second, a analog meter on a fluctuating voltage a analog easier to read, my old Simpson is the one I grab, the digital when it is necessary for a very accurate reading, my best Fluke went bad...

    Speed, Comfort and Age

    78 in a few months, comfort (repeat several times), on my trike sports a office chair with arms, a extra jell pad, all at the same height as I would normally sit. About 15mph on the flat is a comfortable top speed for me, normally I find myself putting along in the 10mph range, no tension, stop...

    First bike idea, how would I attach sprocket to rear wheel?

    I took a circle of 9 ply 1/2 inch plywood, bored a hole to the diameter of the flat end of the taper of the rear hub, put artist oil base paint on the surface of the spokes eye balled the bored hole to the hub, pressed the wood to get the marks of the paint on the wood, took a hand grinder (cut...

    Air Compressor 230V 12A

    www.leeson.com on their tech info elect page the chart they have states 220v single phase motor requires #10 copper wire with a run of 100 feet, (150' #8) but I would go with #8, under a compressor starting load 2 pole motor might not start with a voltage drop that occurs under a high current...

    Winter Riding "Often or Not" Is it safe?

    Living outside of Cleveland Ohio, I road my coaster brake bike back in the 50's every day to high school, rain, shine, snow, sleet, etc. back then not knowing any better as to danger, rapped my rear and front wheel with a small chain that would clear the bike's metal wheel supports to ride in...

    Bike Pusher

    My experience you need traction but get a lot of bounce, you need to spring load it down, or add some weight, like batteries, but then add a suspension frame (to hold batteries), a tire with a lot of rubber/air is a bouncing ball, on a rough road it will spend a lot of time in the air, not road.

    CA v2.1 wire matching for external shunt ??

    I did a parallel shunt to the large current sensing wires, the meter reads current with the decimal point moved over one digit, 90% of the current goes through the external shunt, 10% through meter, on the motor I am using I can draw 250amps, the meter reads 25, fileing the shunt till I got the...

    Cooling a hub motor with small fans inside and some question

    The only way that I have been able to cool motors is with air flowing through the internal guts was to use a pressure type blower, what I found works well is a brush less motor fan (if you can't find one, a air bed inflate type will do but with brushes will have a short running life) that will...

    I got an email from the United Nations

    A couple of years ago my wife received a cashiers check for one million dollars, "she was a prize winner" from Readers Digest, check looked good, took it to the bank to have it checked out, every thing was real but just a few dollars in the account. I wrote void across the check and left it with...

    87 y/o Las Vegas drummer needs trike. What?

    I have ridden a Worksman trike, I powered it (electric motor) to go at about 7mph, (for a friend) that thing is a flat ground only trike, the cg is so high compared to it's wheel base, one has to be very careful of the surface that you attempt to go over, a lady I talked to with scrapes on her...

    crxguy52's golf cart motor controller

    A clean looking job, I did a brush type motor controller years ago before there were chip type gate drivers, my problem was I could not turn the Mosfet off hard enough and the tail left was causing excessive heat to be generated (gate capacitance), I ended up placing the driver transistors close...

    A out of the box suspension idea

    On a trike using 16 inch front wheels, there is not much rubber, and at air pressure almost no shock absorption with that size tire. My thought is to take a 20 inch wheel rim, remove the spokes, lower air pressure in 16" tire, insert into 20" rim with contact cement, or epoxy, inflate 16"tire...

    RECUMBENT WITH MID DRIVE ??

    Hi Kunk; I have been playing around building electric bikes/trikes for years, I powered a Marten Tour Easy long bike similar to your Rands, I found that I needed about 750watts using a split chain system like the Eccospeed, but buying parts and assembling it myself. (A lot cheaper) (That whole...

    how do i fit this sprocket in this shaft of the magnet?

    That motor shaft was meant to slip fit into a planetary gear box, if there is enough shaft left after the sprocket is on the shaft (with motor running) you could use a mototool type grinder with a cutoff wheel to grind a retaining ring groove into the "d" shaft
