VAE experience, practical electric bicycle with trailer

[Christophe]

Our electric bike (assitance) with functional trailer.

I promised you, here's a subject that presents our electric bike experience with coupling based on an electrically assisted bicycle with trailer (solo, difficult to transport something on this bike, it will surely add a rack) . It will soon be fitted with solar load: thus 100% independent to say rd m € € € and the nucleair € p € trol!

A simple but really effective idea!



If I look 4 has wheels so it is almost an electric car!

Budget: € 390 for cycling, for € 120 510 trailer = € in total.

Vehicle Performance:

- Batteries Li-Ion: 24 V / Ah = 8 192 Wh

- Lifetime (given 70% residual capacity): 600 cycles

- Battery life: 30 40 km to the next denivelation (refining, I would say later)

- Consumption (battery at the wheel) electric approximate: 192 / 35 5.5 = Wh / km = (0.0055 kWh / km ...)

- Approximate life of the batteries to 70% capacity: 600 35 * = 21 000 km (some biking are many terminals ...)

To simplify, we can say that the assistance doubles the average speed and allows to pass uneven or traction load (see below) without great difficulty for "Sunday sportsmen" (that we are) ...

We have already made some package delivery to the Belgian Post, but here 1ere my exit to the park Conteners (recycling center)! Yeah, well it has, when possible use this vehicle as a functional transportation!

Exit to the container park by electric bike: my 1st "dump bike"

Loading biking, ca will return or not return?


With a little patience ... and ca organization seems to go!


We wedge the bottles well with waste "shock absorbers" (no shock absorber on the cart):


Shit too optimistic, I can not ...


... But with a good old tensioner ... it closes:


Holy cow, the start is hard:


The wagon is limited to 25 kg load but I think there be widely ...

1er stop the neighbor, 200 m away



Almost there, see the blur sign for the park:

(The park is 4 or 5 km, not far so ...)

Ay, happened:


Unloading current:


Discreet no?

(Photo taken also to show the sorting of plastic bottles by color / type of plastic)

Aye, it's empty, we can go home!


2 things during my visit to the park:

a) a guy wanted to make corrugated Eternit plates, they were refused by the head of the park! (asbestos)

b) another guy threw 4 furniture in perfect condition ...

Voila 1ere for this presentation. It's really cheap and effective as idea ... to see the real life at all ...

By taking a (very) low estimate of 0.2 € / km of the real cost of using a car (the electric cost of the VAE would be 0.012 € / km, 0.006 € / km in France so I neglect in the calculation. ..), we would have to do 500 / 0.2 = 2500 km to make everything profitable (we have already done more than 200) .... and much less if we only take into account the "extra cost" of electrification .... but which will be "canceled" by the "solarization" at all ...

Indeed, I expect in the next day to a small power plant using solar charging panels of 2 5W I came up for the Chinese scooter ...

For now, I will go through small buffer battery + inverter 230V to use the Li-Ion charger founris with the bike when he needs it, otherwise it may flinguer the battery ... I will take 50% of capacity battery plus the onboard batteries.

Following in this topic!

The equipment is ready for the arrival of baby ...

With a trailer, motorists must slow down, thinking a child there.

For pedaling, with a loaded trailer, it's hard? A 250W engine will show its difference?

I see that you do everything an initiatory journey, evolving.
Because the bazaar to take to the dump, tea would be more practical.
You could reproduce the essential elements of your beautiful cart, into a luggage trailer.
The challenge will be to make it as light as possible. This can make a new topic ideas.
Afterwards, why not put more capacity batteries in the trailer?

And later you can filling operations in the Southwest with 2 Bagagères bikes and trailers, with all the paraphernalia of camping ...

[Christophe]

Uh what baby? Already there is a great Dadet before ...

Well with the load that I had (I would say between 35 and 40 kg in the trailer ... but shhh) I simply would not have managed to climb (or very with difficulty) the "small" hill that there is on the path...

I am not sure that on an "open" trailer it is more practical: there is a lot of waste that may fly away you know and it is less visible and probably more dangerous therefore (for the reason you give .. .) ... not to mention the lack of homologation ...

Now nothing prevents "unhooking" at least in part to improve the capacity ...

Otherwise let's not forget that fabric will almost always be lighter than another material! That's why this "trailer" is really interesting ... I think ...

I have used this model of trailer and it goes very well becaufe LIGHT.

[fthanron]

Great about it!

What does this give with serious odds?

In the boondocks where I live, it goes down hard ... it goes like this and I have not seen anyone VAE in the corner!

Good cycling and @ +

PS: is anyone to information about the electric scooter / stirling Dean Kamen? Advantages, production, price ...?

Good evening

there is still progress to be loading level



in any case, this is very interesting and a good achievement.

One of the reasons for purchasing this VAE is that it is foldable and that when stored in an ad hoc bag, it falls under the “luggage” category at the SNCF. All trains are therefore accessible.

In the trailer, we should see if it is removable, but even if that is the case, it may be a bit complicated for one person (no time the judgments of the train and flight risk)

[jessle]

Christine for now it's a matter of organization, but it is doable.

for my case there are two arguments to go to the bike dumped
with a trailer

1 you do not mess see not mutilate your car

2 you can go to each grab your bike trailer;
so when you arrive by car generally is made X path of the car in each bucket

[Christophe]

What does this give with serious odds?

Well, we are still in the Belgian Ardennes, so there are quite a few hills ... "serious" even if it is not the climb to Alpe D'Huez ...

We see very few "functional" bicycles in our area, except the "sporty Sunday" classics (Belgium likes bicycles) ... this may explain that?

Expect I will try to measure (in%) that I came up yesterday ...

Glad you like the subject

[Christophe]

I just roughly measure in Google Earth:

- Elevation: 422 - 384 38 m = m
- Length: m 840

The slope is: 38 / 840 4.5% =

I took the opportunity to measure another slope we spent with this bike and mottrix:

- Elevation: 395 - 367 28 m =
- Length: m 380

Slope: 28 / 380 7.4% =

Unattended, this one should have been pushing (and charging).
