Back in 2019 I bought an ALDI “special buy” e-bike for $999 – the Cell Ultimo Urban E-bike. It is an OK bike, but due to the way the pedal assist works it can be a bit annoying trying to take off on a high gear (as you need to begin to pedal before it works) or go up a hill on a high gear.
I wanted to fix this by adding a throttle. In some states this may be an illegal modification and will definitely void your warranty so please do your own research.
The Cell bikes use the Entity ECU-100 as it’s controller. There’s no datasheet or diagram of the available pins for this controller but researching generic e-bike controller boards (the kind you see on aliexpress/ebay) I found that you wire up a throttle to the “SP” pin.
Remove the two screws on the back of the battery housing where the controller is, then proceeded to label each of the wires while detaching them (this is important, there are many different connections and you don’t want to wire up the wrong thing when reconnecting them).
Remove the three screws on the side of the controller housing and then the four screws on front and back. You can now see the SP pin.
Solder three wires to the controller board. I drilled an extra hold in the plate the writes come out of, fed them through and crimped them to some bullet (socket) connectors.
I purchased a random thumb throttle from ebay for about $20, snipped the end off and crimped on some bullet plug connectors, ran the wires through the bike tube (you want to find something long and slightly bendy to feed it through).
Now everything is hooked up, you can put it all back together and enjoy your new speedy bike.
I have been busy the last couple of months, which means I haven’t been able to do as big a write up for the hottest 100 prediction. I have been running it with just scraping instagram and below are the results. Expect a further write up soon!
I also decided to combine the results of the twitter scraper and my Instagram scraper, which turned out the be a better predictor than any of them. Next year I will have to incorporate a twitter scraper into my predictor.
Below is a summary of some interesting stats about the three automated prediction methods, plus the combination of 100 Toasty Tofu(s) and ZestfullyGreen’s Twitter scraper. I decided to take the results from ZestfullyGreen’s twitter scrape and add them to my results to see if this would be any better. I had a look at my predictions that included duplicate votes, however these performed worse than everything except the twitter prediction, so I have excluded them. This means my hypothesis on excluding duplicate votes (that they make the prediction less accurate) seems confirmed.
The final question that remains is, who truly is the internet’s most accurate Hottest 100 predictor? As you can see below, there isn’t really an answer for this. By my (somewhat arbitary) scoring system, 100 Warm Tunas and myself have a very similar accuracy. I think we will have to wait until next year to really test them.
