VAE experience, practical electric bicycle with trailer

[PITMIX]

Hello
My little experience in VAE, taught me that it is absolutely necessary to acquire experience in troubleshooting to avoid getting swollen, especially if you do not know an honest specialist.

A short question for long-time users of an eBike.
What is your reaction when the battery is hs?
Personal on my VAE it's been 2 years that it is hs and I have not changed it yet.
Unless I have an essential need, I find that investing in a new battery is really questionable (pollution, lifespan ...)

[dirk pitt]

in fact it must be made so that it does not become HS too quickly, which is quite possible with a certain number of precautions.

[PITMIX]

care must be taken that it does not become HS too quickly.

what's not too fast ...?
When we see the price of a battery between 500 and 800 € if it lasts 4 years it is low.
Can you make them last longer?

Incomplete answer.
If you have driven very little during this time, yes.
If you have driven 8000km or more, the cost is then lower than that of public transport which becomes correct given the approval of a VAE (journey time and freedom of the route taken).

Well I admit that I did not always understand everything when the language was technical and with references that I do not know .
I am at least convinced of wanting the engine with the pedal ... and then, full of Ah to be able to make the road.

If your bike is heavy (with the trailer), be careful to mount a reinforced chain.
For autonomy, it is the Wh who count.
Wh are obtained by multiplying the battery voltage in Volt by its capacity in Ah = Wh
So between two 2Ah batteries, the 10V one will have 24Wh of stored energy and the 240V one will have 48Wh and will cover double the kilometers ...

Personally, I try not to have a derailleur whose use is tiresome (noise, incessant handling, need to anticipate, inability to shift gears when stationary ...)
The ideal material seems to me to be the "Nu-Vinci" continuously variable hub but the Nexus, Alfine, or Rolhoff type speed hubs are also good.
I even give a special mention to the Shimano AGT system which electrically drives a Nexus hub to make an automatic transmission (and disengageable in manual).
To try it is to adopt it.

Last point concerning the punctures, they always arrive at the least opportune moment.
Engine, gear hub or derailleur, repairing is always a punishment.
The linear tube tubes which allow you to repair your wheel without removing it from the bike are a big plus in this situation ...

SEB, the maker of pressure cookers announces today the launch of the production of an eBike. Very stylish, the frame sacrifices practicality for aesthetics. Supplied with 2 batteries (?), But at a price of 2700 €, this VAE has disc brakes, but no mudguards ... and the motor is located in the rear wheel; its "more" (?) would be its "intelligent" side, but will surely leave the lover of more substantial qualities unsatisfied ...

Well hello.
So I encourage everyone who can to take up VAE.
It's October and I've filled up my car 3 times and my motorcycle 3 times since January.
I use the bike for 99% of everyday uses: like going to the recycling center, accompanying the hen to a birthday party or transporting bikes...
I have several models. Restricted, unrestrained, gravel, comfort, long distance.
I use quick releases to quickly switch from one bike to another.
Budget level it's modest: 50€ on the boncoin for the trailer

I installed this on a basic trailer. There I found one more suited to this project. An MPPT for 36/48V lithium battery, 2 flexible panels. I tested on my large 36V battery and the regulator had to reset after a cloud on 48V. I burned the battery there from overheating. Which shouldn't have happened but... the BMS didn't do its job for the overvoltage/overcurrent.
Next test on the new trailer and especially a 48V battery. If it switches to 36V there will be nothing to fear rather the opposite

The bar above the PV is really the kind of thing to avoid...

[plasmanu]

Yes, it is obvious that the panel below is covered by 50% by the one above. But it looks sliding, it's probably the road mode and it slides for the stationary mode. Their assembly is made with panels slightly larger than me. I use the length of the panel in the width of the trailer, that solves this problem.
