If you don't need the full charge, and you run it down, just charge it to about 80% using an outlet timer and some basic math:Why keep the battery at 20-80%? I would fill it up so it would be ready to ride next time. How should you do it?
It's been moved. https://ebikesforum.com/threads/error-code-e08.6670/Hi, you might want to start a new thread for this with a title that includes the error code, so people can help. E08 is often the throttle and the hall sensors in it. You can check your connections and make sure each plug is correctly seated. Also, twist throttles can get stuck if they are too tight against other components and keyed throttles seem to have alot of problems all there own. A new throttle might be the easiest solution, why don't you repost and we will see what people who have had this code have to say.
Good to know how that works. I print this out so this old Dog does not forget this new Trick - ThanksIf you don't need the full charge, and you run it down, just charge it to about 80% using an outlet timer and some basic math:
For example, if you have a 10 Ah (Amp-hour) battery pack, and your display shows it's down to 20%, you want to put 6 Ah into it to get it back to 80%. (or 8 Ah)
If your charger's output is 2 A, that takes 3 hours. (6 Ah ÷ 2 A = 3 hours) Set your outlet timer for 3 hours.
As for why, there is a lot of energy in a Li-Ion battery at full charge, enough that it is stressful to the pack to stay there. Think of filling up a balloon: which stresses the balloon more, 100% full or 80% full? Same idea. Also, at 80% full, the balloon still contains a decent amount of energy in the form of compressed air.
Welcome to the forum, Marjory!Just make sure to learn more about the market, as well as real aftermarket reviews. I think this will avoid most of the hassles.
There are SO many brands of eBikes now. Many of them are what I call "mushroom brands" out of China. They copy an existing design, build it in China, sell direct-to-consumer, then don't provide good service.
Reading here for awhile, they seem to be a crapshoot. Sometimes good, sometimes not.
Sometimes the brands get bigger and are OK in customer service. Sometimes, they disavow as soon as the package is shipped.
I don't consider myself a newbie any more, but even after riding hundreds of miles on many different bikes and eBikes, I only have experience with a handful of brands, as eBikes are expensive to buy and expensive to sell. (lots of depreciation)
The guys who DO have experience with dozens of brands are usually reviewing bikes for a living and may be in the manufacturer's pocket, hesitant to point out faults or to let them appear as major as they are. One example: My neighbor here at work bought a Himiway Cruiser because his in-laws have them and were happy with them. His came with a faulty seat clamp. Himiway offered to give him a replacement but shipping was $25, and they considered that to be warranty support. If it were a sponsored reviewer (oftentimes paid with letting them keep and resell the review bike) they would of course ship the part for free and ask the reviewer not to mention it. Or if the reviewer mentions it, that's his last free review bike from that company! When you watch professional reviews on YouTube, realize that when they mention ANY type of drawback, it is likely to be worse in real life than the reviewer makes it seem like. They mention it out of a sense of duty, but minimize it out of a sense of self-preservation.
So newbies, if you're here asking about your first eBike purchase, my general advice to you is to ask first how the brand of ebike you're consider is with regards to after-sale support. If you've narrowed down on a bike from a brand that no one's heard about, it's not a good sign:
Tier 1: A brand that no one's heard about and you can't find more than a couple reviews online from what seem to be legitimate buyers. (as opposed to shill reviews posted by company employees) Avoid these, unless you're mechanically and electrically inclined and are ready for a "project."
Tier 2: A brand that we've heard of, but that is not generally known for great quality or after-sale support. (ex. BikTrix, Himiway, heybike) These are not a great value, as they cost the same as a Tier 3 bike; see below.
Tier 3: A brand that we've heard of and that is respected in terms of bike quality and after-sale support. (ex. Lectric, Ride1Up) At the time of this writing, these are in the $800 - 2500 price range. They range from basic but good quality (Lectric XP Lite @ $800) to pretty advanced. (Ride1Up Prodigy V2 @ $2400)
Tier 4: Just like Tier 3, but with local shops/dealers. (ex. Aventon, Rad Power Bikes) At the time of this writing, these are starting to come down to the US $1300-2000 price bracket. With Tiers 3 & 4, it would be good to have some mechanical know-how, but you can probably take them to a shop that is more or less local. (might be a 100 mile drive in some cases) Rad has mechanic vans, for instance. Aventon has local dealers you might not expect; I bought mine from an Indian motorcycle shop, for example. If I had a problem I needed help with, they may have to consult with Aventon, but I'm confident their mechanics could handle anything I couldn't.
Tier 5: A "bike shop brand" that has widespread support and superior quality. (ex. Trek, Electra, Specialized, ) These bikes are without fail more expensive, because it costs the manufacturer money to support local shop who supports you in the long run. Buy with confidence, once you have the money together! These commonly start now at $1800 (for a no-frills hub driven bike) and go up to $14k. (for a high-end carbon road eBike)
16 December 2024 Addition: There is something that can happen called "ghost pedaling" that newbies should know about ahead of time. It means that, due to the gearing choice of the manufacturer, the rider can't pedal fast enough to keep up with the motor. This bothers some people enough that they look to raise the top gear ratio so that they can help the motor. While this is an admirable attitude by the rider, he should realize that the rider's input doesn't amount to much at speeds over 20 mph. Also, if the gearing is changed at the front sprocket (chainring) then he will lose out on the low gearing, so that if the rider runs out of battery, it may no longer be realistic to pedal the bike home.
Ghost pedaling can also be done intentionally on bikes with older-style cadence sensors*. The rider would set the Power Assist System level (PAS) to a given level, but then pedal slower. The bike's motor controller will sense the rider is pedaling, then use motor power to accelerate the bike to that preset speed. The bike doesn't know or care that the rider is not pedaling fast enough to help, only that he is pedaling and that means it's OK to provide the power needed to get to the given speed.
* I said "older-style" because modern cadence sensors can be set up with a power limit, rather than just using whatever power is available to accelerate the bike up to the set speed. This makes it feel more natural, but without the expense of a full-on torque sensor. (torque sensor-equipped eBikes provide power in proportion to the power the rider contributes himself.)
Great insights! Your tier system really helps in understanding the eBike landscape. It's crucial for new buyers to consider after-sale support and brand reputation, especially given the wide range of quality and service levels out there. Your tips on ghost pedaling are also super helpful—definitely something to watch out for. Thanks for sharing your experience!There are SO many brands of eBikes now.
