Pursuing EV Mobility for my Cargo Bike

1424559792

So, here's the finished Schwinn bike, remodeled. Replaced handle bars, new rear wheel gear set, super low gear, stock rear wheel rack removed, fenders and chain guard painted black, new double cargo baskets attacked.


Total professional "tune up" completed. Adjusted to fit me. Runs perfectly. Yes, it was once a girl's bike, now its MINE. I need a "step through" frame style in order to accommodate the large cargo baskets.

Now building new wiring harness to install motor, controller, throttle and batteries.

Completed major improvement yesterday. First this "department store" bike, a Schwinn ordered from Amazon, is poorly constructed. Parts are generally inferior to any bike on the road today. But it is new and the frame meets my requirements. I paid for a general tune up at a local Bike Shop called Single Track. They did an excellent job. I also paid for an improved rear sprocket, better quality metal and bearings PLUS a custom larger than usual lowest gear.


My experiments demonstrated that there will be times when I want to "assist" the hub motor with my own pedaling effort. I need the torque of this lower gear in order to help.

I've adjusted the new handlebar and the seat so it matches my other bike.

Photo above shows the bicycle whose frame I am adapting for my EV cargo bike. It arrived with a wide "cruiser" handlebar. It is too uncomfortable for me, even hitting my leg when I make a turn. I'm swapping it out for a handlebar type that you see in the lower photo.


When I did this the ride was much more comfortable and the bike fit me better.

I will be working now on my brakes and gears.

Comment: The proprietor of one of the bike retailers I visited recently for support made disparaging remarks about my "department store bike" and that his mechanic prefers not to work on them. I wanted to remind him that in the wellness doctrine the best bike for your health is the one you ride. He is focused on hard core mountain bikes.

Someday, he'll be retired too.   :-)  The sweet bird of youth is short-lived.

It must be apparent by now that I am combining more than one bicycle into my own preferred and primary cargo EV bike. The used bike I acquired with the hub motor has a rear wheel coaster brake and three internal gears, only. The gear shifter is awkwardly mounted on the handlebar and difficult to use. I'm not happy with any of it. The new basic bicycle I purchased has seven sprockets (gears) on the rear wheel, none on the front sprocket. This is the combination I prefer.


On my recent road test using the electric motor I discovered that if the hill I'm climbing is steep the hub motor will require my help. I want a range of gears for this moment, much lower and diverse that the three that came with this used bike. So, I am moving the hub motor over to the newer bike.

Under consideration... these heavy nylon basket liner bags are built for this. Might be the perfect solution for holding my batteries and future cargo.


My primary objective with this project is to provide myself with alternative transportation when my wife and I need food and supplies from local stores. Solutions on a budget it pragmatic.

I found this high quality metal basket on the internet. Talking to other cargo bike riders I've learned that cloth saddle bags tend to flop around when filled with anything heavy.

 Unconfirmed, it is my strategy now to split the batteries into two packs and to place them in the bottom of these baskets.

As I prepare to re-wire and install the twelve volt batteries I find that my vocabulary and tool set are shifting, good for my gray cells I assume. In my ambition I've decided to make an effort to lower the center of gravity of the bike as these lead acid batteries are very heavy. Traditionally, I find them mounted as a block on the rack over the rear wheel. This amount of concentrated weight makes the bike top heavy and most kick stands no longer work. The bike falls over. The previous owner of this bike I've acquired just let it fall on the ground or he wrapped it around a pole or tree.

Just acquired an asset toward my personal EV mobility and fodder for the content and theme of this web site. I've received a used hub motor installed on a used 26" bike. Batteries have tested well and are all charged up. Complete equipment set still functions as nearly new, lots to work with. I hope to record herein my development and evolution as I build for myself an EV assisted mobile device.



An email exchange with the supplier of this hub motor asserts that "there is no fatigue factor on this motor as there are no moving parts. Inside are magnets and copper wire only, the bike wheel is the motor. Power and/or weakness are determined by the batteries." (Remember this statement for later) This also applies to range per battery charge. This is a 600w motor and I'm going to drive it with a 48 V system.
