My new Bamboo GT and a broken rib

Good morning guys, Giacomo from Italy here.

Last week I bought the new Bamboo GT from Evolve Germany and shipped here in Italy. I used the skateboard on the weekend and unfortunately yesterday happened an accident that caused a broken rib resulting in admission to the emergency room.
Now I need to understand what happened.
These are the facts: in Fast mode with 24 km / h speed after you press the left button to switch to Eco, the board suddenly had a sudden slowing down, almost as if there was a stalemate in a split second. . this of course caused me the fall that cost the broken rib.
What the hell happened? I read 10 times the manual and they said to use the 4 speed as a gear, so I did.. while driving I pushed the left bottom from Fast to Eco and boom! Broken rib... auch!!

Battery: 30%
Temperature: 2°
No water etc, yesterday was a sunny day.

I purchased this skate for fun and to go to work, not to end up in hospital.
I really want to understand what happened ..

I didn't wear an helmet (I know I'm an idiot!, after yesterday I've ordered immediately the helmet, Ruroc white inferno), fortunately I did not hit my head or my face.

left button sets the reverse mode... furbo!!
auguri di pronta guarigione

 

Absolutely no! I have the new remote.. they made an upgrade a couple of month ago.. left button sets the reverse mode with OLD remote, now you have to go on Slow and than you can sets the reverse..

PS: grazie per gli auguri..

 

You should contact Evolve Germany, they are very responsive and helpful. I bought my Bamboo in december (probably same patch as yours) and have problems with my remote too. Sometimes it seems that the remote isn't connecting properly with the board causing lags and delays. Most of the times the connection seems good and I don't have any issues. Still, I'am always worried the breaks kick in and send my flying to the ground/ car/ you name it...
Evolve Germany is sending me now a new remote after they tried to fix my old one. Anyway I hope you get well soon and figure out your issues with the board.

I made a short video to show the input lag

 

Thanks man for the feedback... well, my remote works pretty fine, I thought that weren't no lags or delays but yesterday as soon as I pushed the left button to go on Eco mode I had that terrible experience. A broken rib hurts A LOT!! The only thing I noticed is that sometime seems that the graphic with battery level and the signal disappears for a second. Only the graphic on the LCD, no trigger issues.
I can't really understand what happened..

BUT I've just made some test: when you try to change the mode (for ex from Fast to Eco: you are in Fast, release the trigger to neutral position, push the bottom, go to Eco) at that point, sometimes, there is a little lag between the board and the remote, half of second but that delay it's very very dangerous.

My suggestion is: ALWAYS change the mode when the board is stopped, NEVER EVER change mode when you are 'driving'. The big problem is that on the manual they said the opposite.

I'm a little bit confused.

 

I had the same problem with my first remote too. They tried to fix with changing a resistor in the remote. I think they just made the output signal stronger and were hoping that it would fix the problem. Sadly not, but it got definitely better.

What do you mean with little lag? I think it's normal that the board doesn't switch instantly to a different mode after pressing the button. In my case it takes at least one second if not longer. While switching modes I don't touch the buttons / trigger and double check if the board switched to the mode I want. After that I gently accelerate.

Contact Evolve Germany and let us know what they say.

 

Ok guys, we made other checks (with the help of my brother because I unfortunately can not move from the couch because of the fracture).

I think we found what caused the incident: we lifted the skateboard off the ground for about 20 minutes changing the various speeds. Well, at least 7/8 times there was the problem that made me fall to the ground... during the change, the board had a delay of about one second then resumed at full speed, this yesterday caused the fall. When I switched from Fast to Eco the Bamboo had this delay and as soon as he regained the speed I ended up on the ground... result, broken my rib.
To be onest, that's not good at all. Before the Bamboo GT I had a Yuneec e-go, very 'easy' e-board, very slow but safe... I bought this beautiful Evolve just for fun not to die...
Please forgive me but I'm a little bit nervous, having a broken rib means 20 days at least at home, doing nothing with a lot of pain.

 

Thanks Alex.

Just contacted the Evolve DE, we'll see what they say..

 

I wish Evolve would do something about this mess, there's quite a few issues they're failing to acknowledge and fix with their product. If they ignore it more and more riders will get hurt bad. Fix the lousy remote connectivity to the board from the remote, fix the defective motor controllers, and have an option that disables reverse. You can queue up remote events and not even know it, then once you're moving forward the board will appear to jam itself into reverse. Reason being is there was some lag / drop in communication with the board, then all the events get processed such as the multiple left button clicks, then bam you're in reverse without any idea. Same can happen when moving forward in GT, you have the throttle pushed forward more and more, not that much of a response, them bam full GT mode out of the blue. I too got injured bad from this crap. Still healing and still don't trust the board after they replaced the remote and swapped out the motor controller.

Sorry to hear you got hurt.

 

Now I'm definitely scared about this board.

Anyway, Nick from Evolve Australia send me a message this night:

"Switching from “Fast” to “Eco” is dropping power. If you switched while accelerating, the drop in power would cause the board to stop accelerating and coast. Is it possible the change in accelerating force threw the rider off balance?"

Now I'm waiting for Evolve DE because they sold me the board..

 

I hope your rib heals fast and you're rockin that new board and Helmet soon!!

 

Well honestly it sounds like what you experienced was just from a poor design of the board. But I'm curious what happened. When you switch up or down with the exception of FAST to GT and GT to FAST, the rider needs to put the trigger / throttle to neutral position to downshift or upshift. A rider in the forum found that this is not done in GT to FAST and FAST to GT shifts. However, with my board its dangerous in design with that latter shift (up). If I shift from FAST to GT, sometimes the board will 100% shutdown its throttle. So not good since you're preparing for that high torque in GT. I don't know if its just my board or if others have this and its GT wide of an issue. I had a thread on this but didn't see anyone come back with details. But in your case, the way I thought things were to work is that you had to hit neutral before the down/up shift. If I'm wrong with any of this stuff guys please correct me.

Now when you said you pressed the left button to go from FAST to ECO and then there was a sudden slowdown. Are you saying that the regen brakes were applied or that you lost some acceleration and that the momentum of the board decreased? What I would expect from a drop from FAST to ECO would be a drop in momentum. However like I said, if you kept the throttle / trigger in the same position, hit the left button to goto ECO, the board should not had dropped into ECO until you hit neutral. Now if you were boarding that 20% battery level, you said you were at 30% (Was that with or without throttle, the battery levels are inaccurate and based upon what you were doing at that moment, another bad design). The board will drop down from FAST or GT if you hit the 20% battery threshold.

The issues I described were / are with RF and mainly the remote and RF shielding properties of the board. Much of my choppiness behavior was from a defective motor controller. Board was smoother after that, but still unpredictable due to cutouts, buffering of commands that lead to unexpected behavior. And the issues I've had seem to be what people say a small percentage of people experience. I think I got the worst case board in every way and form. I like it but I wish they put more attention to quality and safety in their build and test of the board, same with their troubleshooting which isn't the best in my opinion. Now they've gone cold on email responses. When I get time I'm going to be putting an antenna extension on the GT's Bluetooth Controller in the board, routing it outside the board and on the top. This should eliminate my issue 100%, if not, greatly reduce it. They put an RF shied all around that antenna, I have a Carbon GT, and the whole board is carbon fiber. Carbon Fiber filters and blocks wireless signals and is really really good at that. But you have a BamBoo, so much of what I experienced in crazy gremlin behaviors as I said may not apply to you, bamboo is no that bad on RF signals like CF.

Thank you so very much man..

 

The broken rib(s) will take about 6 wks to heal (give or take) - speaking from experience when I got chucked off my Bamboo GT

 

Ouch, I hope you are well again. What happened?

 

Similar to Wiztecy - came into his thread here: (RF problem with remote - throttle stuck - went for a ride...)

Got my remote replaced - need decent warmer non-winter weather to test properly

 

Damn!
