glad to see that my E-onda board built can also claim to be "world lightest" E-skate with its 6.4kg :wink:

Damn, sold out on day one. Looks like 4-6 weeks for shipping. Im wondering if I made a mistake ordering an evolve. At 699, they have definitely nailed a very attractive price point. I may buy one just for kicks once they become more readily available. Still wish they hit closer to 15mph. It looks great though! Im eager to see what the first reviews say.

 

[torqueboards]

How many did they sell? $699 is a decent price for one. I do wish the speed was faster 20mph would be perfect. What did you pay for your evolve which one did you get?

Are they Lipo or LiFePo?

 

[whilechukwuzout]

I ordered an evolve pintail for $1099. The carbon one looked nice but the battery is too big (capacity-wise) to take onto an airplane. Something I had to keep in mind because part of why I want one of these is to have something to ride around when I travel to China. Its funny, Yuneec's headquarters is about 20 min from where I spend most of my time when Im there.

 

[whilechukwuzout]

Are they Lipo or LiFePo?

Good question. Due to liability I have to believe they are LFP. The amount of money you have to spend to make regular lico (li-ion) batteries safe from failure modes is substantial.

a review with a nice review film!

The only con for everyone is the speed

 

[666yeti666]

any more news ?
A friend is interested and would like to judge about the maximum speed of 12mph and if that's enough.

My own board will do 16mph max, but honestly I ride with an average of 9 to 10 mph ... so 12mph could be enough for the majority of the people

thx

Hi

I received my E-Go Cruiser board last week and I am very pleased with it. I think the speed is enough, but maybe it's because I am a beginner.

I do however have a discount code if you want to order an E-Go Cruiser from http://www.e-go.com.

USA: KM20140412 - Gives you a 50$ discount
Europa: KM20140412 - Gives you a 35€ discount

Best regards,
Klaus

 

[666yeti666]

Hi Klaus
Thx, this will save some bucks.

For 600 euro's this is a real fair price. Also it is very light.
Do you have experience with bridge/hill climbing ? Does the speed drop rapidly ?

Thx
Sebastien

 

[kvers]

Hi Sebastien

I have not done big hills, since I live in Copenhagen and we don't have that many. But off cause the speed does decrease a little when climbing a hill on the board, but not significally on the smaller hills I have cruised on. I'm very pleased with it and it does excellent carving. The price definitly doesn't conflict with the quality, which I would say is very high.

I want to buy the truck with the motor...I feel like its a standard brush-less. I spoke to someone at the company but they were hesitant to tell me that I could get it and use it on a home made kit. Its a pretty nice mount...looks like it could easily be modded...anyone else have this idea or am I just crazy?

 

[666yeti666]

Hi Klaus, ok seems pretty ok for the 'average city cruiser not living in san fransisco'.
Crossing a bridge now and then should not be a big issue.
Thanks
Sebastien

It would be nice to see some tear down pics of this board. Anyone want to open it up for us? The motor/truck combo might not be a bad deal for people. The trucks are just chinese blank pro brand. You can get two for $20 shipped on ebay, which would be cheaper than buying their front truck for $50. They are the sames trucks I've used on my builds. I too am most curious as to what size motor they are using. It is cool of them to offer parts. Most other brands are lame about that ie. Evolve. It might be worth it to build your own from their parts.
160 motor/truck including belt, sprocket
20 front truck off ebay
50 HK batteries
100 E-go ESC
100 Wheels includes gear
40 E-go remote
Add board
Total is 470 plus 25 shipping to US
Not too bad if you can get it to go over 12mph. You could forgo their ESC and remote and mix in the HK stuff for an even better deal. I imagine the motor is not what is limiting the max speed.

 

[lookitsneil]

I was actually planning on just getting the mount, removing the motor. From what I've seen it looks to be a 63mm brush-less that they are using. They have their motors wired to one input, easy enough to separate out. and from what it looks like I'm pretty sure I could 3d print a sprocket for an abec 11 flywheel that would fit their belts. I feel like with enough ingenuity you could have a complete set up for much cheaper. That is if the mount can be backwards engineered.

So far I've tired the 3d printing solution for the entire setup and learned the drawback of PLA Plastics and the pain of ABS plastics. That's why Im looking into other alternatives. I wish I had a cnc milling machine haha.

 

[torqueboards]

I wonder if that e-go remote comes with a receiver. That would be awesome.

 

[lookitsneil]

Oh man, that would be a great hack for the builder community. We could stop using Wiimotes haha.

So I was checking upon their mentioned range of 30km which, I think, is a lot. How do they do this ?

The charger input wants to have a voltage of 29.5V , which would mean 7 cells lipo (charging voltage = 4.21V/cell) . 2000mA is also mentioned; I think this is the charging current

A little above that are the specs of the battery :
7.8Ah, 900grams
(Charging time of 3 to 5 hours , well, that would make sense with 2A charge current)

The weight of this lipo is very low. I’ve checked around and for 7s 5000mAh the weight is getting quickly around 1000grams already, mmmm ......

With my own board, which is quite efficient already, I’m consuming 375mA/km with an average speed of 15km/h (my boards weight = 6.7kg)
When I want to drive 30km I would need a pack of 11.25Ah , which is half more capacity needed than the e-go …..

So, how do they do this ….. ???

I would like to know the gear ratio, so we can calculate the motor kv. Maybe it is in the secret of this motor why it is running so efficiently …. ???

Sebastien

I think you mean 0.4Ah/km...
without being sarcastic, you could double the capacity OR ride slower... which is maybe their choice...

Ha ha , that's a good one ... :lol:

 

[666yeti666]

I did some rough assumptions and calculations and I think the motor could be a “standard 130kv” one, so no “special wind” which makes it cheaper of course

Assumptions :
gear ratio = 1:2.5 (eg. 15/38)
5% losses
Avg cell voltage = 3.5V

Facts :
90mm wheels
Max speed : 20km/h
7 cells lipo
