Prius Tech Support

So I feel like one of the very 1st internet eMail memes today. I drive a Prius for work, it's about a nickle a mile for gas & in a day that tops 200 miles it's near a dime per mile to own, insure & operate. Not accounting for tolls of...

Object of Lust

I really really want one of these. I'm a fan of robotics in production, when they're used to increase capacity instead of to cut man power. We had payroll rich manufacturing & it had to be leaned out, that sucks for those caught in the squeeze....

Snow Ride?

There's a couple inches of snow on the ground & some ice on the road under it. It's only 20F outside, so it's within the tolerance range of the motor/battery. The motor worked fine for the few minutes I was out. I didn't change tires for...

Power Generation

Recharging an EV is the biggest problem with batteries, they take a long time to charge or you do significant damage to their over all lifespan. This is the simple reality of it, it has to do with some of the more basic laws of physics &...

Cold Weather Battery Test

The battery is rated to -10c. Today I rode in -1c to about 10c, it was windy so it's difficult to estimate exactly the range difference in cold weather vs hot. I will give a rough estimate of 75% or better of the maximum range in cold weather. I don't...

Gear

So gearing up for Winter cycling is expensive & the speeds I travel I need good gear, the wind chill is significant. I was looking at a nice pair of winter cycling boots. The cheapest I found were more than $150 & what everyone agrees are the...

Apples to Pears

They're pretty close as far as fruit go. Similar texture to both the meat & skin, similar sugar profiles. Yesterday I rode with a friend who had a mountain bike that weighs 1/3 of what my bike does, it has no motor. I rode at his pace &...

Responsible Usage

An hour long bicycle commute is not for many people, especially if it's just the one way. Most of us aren't fond of an hour long commute of any sort. Total Usage used the whole battery for a strong 40 mile ride. A ride that would have been...

Wintergreen Mtn

This was a big test for the bike. I failed miserably but, the bike did okay. The biggest issue is one I nearly fixed, my tires are huge, I should have put on much smaller lighter road tires. I was overgeared for the ride I really needed at least...

Figuring for Range

Range is the 1st question a shopper wants to get answered when shopping for an electric vehicle, it's the question they will NEVER get a satisfactory answer to, range on an EV is something you figure from riding not before. Gasoline vehicles have wide...

Maintenance

Today I did my 1000 mile maintenance. I took the wheels off & re torqued the axel nuts. I took off the battery rack & cleaned the frame, I unwrapped the wires & cables then restrapped them all with new cable ties after cleaning the...

Zero Watt Ride

So I have friends who consider an eBike "cheating." If I were riding with others or in a race where I was the only one with a eBike... yeah that's cheating. I point out things such as some choose to buy a several thousand dollar carbon frame & the...

A Good Ride Today

I am developing strategies for regenerating power more efficiently. Today I rode 40 miles on 2/3 of a 500 wh battery, it looks like over reasonably varied terrain I can expect 50 miles or more, less the more I carry. Next week I will try to get up to...

Range Testing Is Nearly Done

With the Heinzmann Direct Drive 500 watt hub motor using my own parameters for the programmed controller & a 1/2 kw hour battery on a bike weighing 60# including motor & battery along with a 200# rider in slightly better than average condition...

You Get What You Pay For...

That's a pretty common reality, you don't generally buy glass & get diamonds. I have a friend & that very easily could have read I had a friend... I have a friend who wanted to build an eBike & felt he could save some money. He got...

Pedelec Update

I've hit 42 mph & it seems to lose sufficient torque to assist somewhere around 40. The battery is 1/2 a kilowatt hour & I can get ranges above 40 miles so my "fuel" costs about 6 cents a "tank." It certainly costs more in reality because...

No Pics Yet But, It Is Fast

It's ugly, the wires are not well stowed yet but, it's fast & I am well pleased. It hit about 30mph on the initial test ride. I rode it a couple miles & the battery meter didn't move even though I was using max assist. I am very...

Ship Date has Finally Arrived

My eBike kit is finally on it's way, it's the 1st of it's kind in North America & I am thrilled to be the one testing it's capacities.

Sound Waves to Create an Envelope

The #1 undeniable attraction of an electric vehicle from an aethetic perspective is it's quiet. They are generally spartan compared to other vehicles in their class & this is alos it's worst safety characteristic.   Horses clomp, engines...

Batteries as Suspension & Crash Absorption?

So the idea seems far too simple to work but, here goes since I certainly don't have the ability to develop it & would love to see it.   We have gel batteries they're full of a , gel it's highly viscuous which makes it an ideal shock...
