My "New" Ebike

[gromike]

I recently purchased this 15 year-old ebike for $250. It's a Giant Twist Freedom DX W. Outside of one of it's 2 batteries being toast this thing is as if brand new. Figure it's a 2009 model.

I have been riding it around and it works really well, albeit it is slow. I guess back in the day, going the leisurely pace of a standard bicycle with a bit of electric assist was a novelty, and something that people would lay down $2,200 of 2009 dollars for. Who ever bought this hardly rode it at all, but thankfully stored it clean and dry.
I'm thinking of recelling the 2 batteries and keeping it the way it was.

Very cool! It even has front suspension, rack, and panniers! A front hub motor, is that right?

Is that sneaky cat letting the air out of your tires ??

That's a dad-gummed porcupine. He looks harmless after a veterinarian removed his quills, but salt is porcupine catnip, and a porcupine will chew up a bicycle tire if sweaty hands have touched it. I once emptied a 15-shot semiautomatic rifle by lantern light at an attacking porcupine 10 feet away, to no avail. That's why I learned to shoot from the hip, aiming with my left index finger. No more wasted shots.

Yes, though the batteries are in left and right panniers and take up some of the room.

Welcome to the forum.

@gromike has been here for quite a while.
It's just his latest purchase that's new.

He usually buys a regular bicycle and adds a motor kit to it.

I think this might be his first purchase that was already an e-bike when he bought it ??

Thanks for the heads up. I really must start paying attention. LOL

I remember going to my great uncle's hunt camp when I was 16 yrs old, and my uncle told me how some critter (a porcupine, I think he said?) had chewed it's way into to hunt camp and ate the toes out of his leather boots to get the salt.

Lots of beasts get killed on roadways when they are licking the salt off the roads.

This is a mountain goat licking salt off the underside of a mountain.

A very nice find, and worth 250 bucks, You could probably rebuild the battery as a 28V12AH 9S-4P and have a little more power w/o blowing up the controller.

What about charging it ??

My bench power supply could do it, but are there any 28V chargers ?

Grin Satiator. I believe Gromike owns one.

Very interesting and looks to be in excellent condition... but do you really want to ride this instead of one of your more modern bikes?
I'm not sure I could take that far a step back now that I'm back in the future.
More (actually less) power to ya! Enjoy!

The Grin Satiator is 4-5 hundred Canadian dollars.

I have a $180 3 amp Bench charger that I use to stimulate and satisfy my batteries manually.
They seem to like it that way ??

My batteries are OK with the little 3 amps charge they get, but maybe the $291 5 amps version might really get their rocks off (or ovaries, ?? I don't know if my batteries are male or female, or if I should treat them differently??)
They seem to like it and always give me lots of miles without me pedaling at all,..

I personally don't want to charge my batteries at 5 amps, so I don't want the 5 amp Bench Power Supply that costs $111 more,..

 

[Gionnirocket]

Seems the original batteries for this bike were 24v nominal.
The Satiator bottom rating is 36v, so no go.. But I do believe the current is variable on it so you don't need to pump all 5a into a battery if it is usable.
So is the correct charger for 6 cells in series? 25.2v full charge voltage?

edit:... a Google shows a 7S 5P configuration with a 29.4V charger.

It wouldn't be all that difficult to install a new controller and higher voltage battery. It's just that the design is so well integrated I'd hate to mess it up. As is, no one would desire such a slug. Nonetheless, it is enjoyable to ride.
