Senada DRIFTER Compact Fat Tire 500W E-Bike (Black) Expired

I checked youtube review and it goes 28mph throttle only. Can anyone confirm? Because most ebikes limit at 20mph throttle unless you pedal

Quoting you, but there are others with similar questions.

For the ghost pedaling, you can upgrade to a Litepro 58T crankset [amazon.com]. That crank is nice for 55 bucks, but you can buy it for less than $30 from AliExpress.
All of these bikes use the same square taper bottom bracket and this makes a crankset swap extremely easy, even to non-bike mechanics. A square taper puller [amazon.com] is only $8 on Amazon and I swear it takes 2 minutes to swap each arm. They are simple devices:
1) Unscrew the crank center cap with a Hex wrench.
2) Make sure the wrench supplied sits freely between the silver part and the black part.
3) Use the wrench to screw in the black crank puller part so it becomes tight with the crank arm you are about to remove.
4) Slide the wrench back onto the silver part to start screwing into the black part. As it goes in, it eventually rests upon the bottom bracket. Keep turning to keep screwing it and it will start pulling the crank arm away from the bottom bracket. Lots of YouTube videos if unsure.
5) Pop the crank arm off and unscrew the black part of the puller.
6) Put the new crank arm on and you simply use the center cap you initially removed to install it. You just screw it back in with the same Hex wrench and it will push the new crank arm against the bottom bracket. Use 40nm of force or realistically for those without a torque wrench... just wrench it down pretty hard.
7) Done.

Enjoy not ghost pedaling until about 24mph+. Additionally you'll actually use the low end gears once in awhile as well. Even from Amazon at $65 all-in, it's a no-brainer upgrade.

As for the battery level indicator. I don't own this Seneda bike and unsure on the controller/display, but if it has a Voltage display option that is the true battery level indicator. This chart [google.com] will show you the more realistic numbers to look for. If your bike doesn't have a voltage readout available then you have options still. I would wager most here aren't trying to become junior electricians so I'll skip the tutorial on adding in inline 12v battery monitor, but you'll still need to own a multimeter.

This one is $10 [amazon.com]. Plug the black prod into the center port and the red into the right port then turn the dial counter-clockwise a few steps to the "200v" settings. Here's the cumbersome part...
1) Charge battery to 100%. Feel free to pop it off the bike and look for the pin outs, they should have two labeled for positive (+) and minus (-) on the terminals. Put black to the Neg- and red to the Pos+ and se the reading. Should be 54+ volts.
2) Ride the bike until the first battery bar disappears. and instantly pull over, pull the battery and check the voltage again. Follow the chart I linked. Write that down until you memorize it, but that is what the actual percentage of battery you have left will always be.
3) Do the same for each bar that drops.
4) Put those numbers somewhere you can find or see them easily until you have memorized them. That way you'll have better knowledge on what voltage those battery bars actually mean when they are first discharged.

Note it is essential to take the number when there is no stress on the battery (not being actively used). The bike should cut out around 42v, about 20% usable battery left. If it doesn't, know that 39v, 99.9% of the time is a battery so dead it cannot be recharged and revived. Once you hit 42v, you are on borrowed time. Even thought 42v means you have 20% battery left, every percentage point is more chance your battery is going to suffer permanent damage of some form.

Additionally since I don't know what display is used here the general way most run is you are have 20% battery not on the last bar showing, but when the last bar starts flashing. Of course you'd have to test the batter with that multimeter when that happens to know for sure.

Both these steps can take an hour or so the first time, but I highly recommend you just do them. Imagine not knowing how much battery you actually have for the life of the bike compared to just taking the time to figure it out and actually knowing the entire time... not getting stuck on a dead battery once will pay for itself.

I should have ordered through amazon again dammit! 😭

Could you share a link, name or image of the seat post?

If anyone cares, Walmart has it at the $679 price point . I for one do not care, I was locked in at the $599 price, however, if someone cares, it's available 🤣.

Anyways, has anyone heard when they might restock this?

Do you also need a longer chain?

https://www.amazon.com/BICYCGEAR-...th=1&psc=1 [amazon.com] As an example. there are a bunch on amazon and Ali Express

Don't worry NO one got anything during the Amazon fiasco.

what was the Amazon fiasco about?

Bunch of e-bikes on Amazon that were on sale that never shipped. Amazon said they were going to ship and then told everyone their shipment was lost and gave everyone a refund. Was an interesting time!
