It feels like the bearings are squealing…
So there are two seperate questions that need to be answered:
- Can it be done
- Should it be done
Can it be done. Yes. you would lift the rubber padding under the bolt positions. That would expose the bolts that hold the trucks to the baseplate of the drive. You would also need to completely disassemble the drive and run long silicone extension wires for all six motor phase wires and for the 12 sensor wires. Then you coud mount the body of the drive to the center of the deck and run your silicone wires to the trucks and motor assembly. You would want to have excellent solder joints so that they do not break. If a wire broke during operation you could damage the speed controller or you could be injured. But yes, it is possible. The most similar thing that I did was to build a six wheel drive Landwheel. The last drive I disassembled, mounted the drive on top of the deck, ran the wired through the deck to the hub motor assembly below. IT worked great until one of my solder joints broke for a phase wire. I damaged the speed controler because the two functioning drives dragged the disabled drive for quite a distance. So that’s how I know the importance of the solder joints not breaking if you extend the length of all the wires.
The second question is should you do it. So, I have never ridden on a set of waterborne adapters. However, I can propel myself by tick tacking all day long and at what is likely the same speed that you show in your videos – possibly faster because ticktacking throws alot of momentum and thrust at the wheels.
You can see abit of my tic-tac propulsion at several points in this video:
So while I have no waterborne experience, i do have some analgous skills an experience when it comes to using a pumping action to propel a manual skateboard.
I can tick tack all day long on a manual skateboard. I can do it on a revel kit board also. However, I can only do it for a relatively short distance because of the extra weight. And I suspect that you would discover something similar if you combined the Revel Kit and waterborne adapters on to the same deck. When I tic tack on my revel powered decks, it is mostly to make sharp turns. I can propel the board wiht tic tac movements only – but it is exhausting because of the extra weight and additional drag from the motor assembly. So on this basis, I suspect you would also find pumping to be fairly exhausting with your waterborne adapters combined with a revel kit drive.
There is one more aspect to “should you do it”. That aspect is high speed stability. I recently mounted double kingpin trucks on the front of a revel kit powered deck. It seemed cool at first. but then at reletively low speed, I experienced a speed wobble and almost lost it. By relatively slow speed, I mean slow for the revel kit. I was traveling faster than I can tic tac. The revel kit is capable of considerable speed. For that reason you want a front truck assembly that relatively stable. Double kingpin trucks are a big no-no in my opinion. I suspect you would also encounter some pretty wicked speed wobbles if you tried to combine revel kit speeds with the agressive turning circle of the waterborne addapters.
So without any direct experience with the waterborne adapter–but based on the analgous experience that I have wiht tic-tacking and double kingpin trucks, I suspect you might find yourself putting together a board that was capable of surf pumping and electric power --but not very good at either.
My advice would be to put together two different set-ups. One that you already have – great for surf style pumping. And a second set-up that is great for electric longboarding.
And having said all that, I could of course be wrong because I have no experience riding the way that you ride in your video.
Looks good how much does this cost? Also does it cut out?
Can you answer some of the questions that asked earlier? Are you riding on the stock wheels or did you switch to different wheels? Which ones? Did you try switching back to the original wheels?
I suspect your motor is not rotating on the same axis as your wheels. The clicking sound would be consistent with that. Try running some of the swapping experiments that I outlined in my earlier response. This should help you to isolate the source of the wobble. Motor? Adapter? Wheel? Axle?
Are you referring to the Jetboard? $10,000 USD for the board and $5000 USD for extra batteries. It runs for 20 -30 minutes at top speed with a heavy rider. I’m not selling them or anything like that. This is just what I learned during my vacation.
Nono the kit at the start I don’t need a motor on water unless its on a boat.
Apologies! The wheels are standard 90mm that revel sent with the kit.
The problem now is a different one than the last squeaking that I had. I checked the motors with and without wheels to see if things spin correct and uploaded videos of the left motor in my post above. In short, with wheel it looks like it’s not completely round but without wheel the motor looks like it’s spinning fine. That makes debugging/isolating this a bit harder.
But it’s now a different issue from before (with different sound) and only happened outside after using it for a bit, not in my apartment when I have the board flat, so a quick swap and see what happens isn’t so easy. I’ll see if I can take things apart again but I’m out of my expertise here
yes this revel how much?
ok, so you were talking about a different video than the one that was immediately before your post.
So the Revel kit pricing is on thier website.
Good Thanks
Try swapping the front wheels and the drive wheels. Then try swapping adapters left to right. That’s two seperate experiments. If the wobble stays with the same motor and axle then you either have a wobbly motor or a bent axle. You might have both. A bent axle could force a wobble into a motor and maybe the opposite could also happen.
Thanks! I’ll do that and report back
I’m not having any luck with my kit.
I swapped the front and back wheels and nothing else, never opened the motor or touched the electronics. Then wanted to go outside to give it a try
Immediately something wasn’t right. When I move the accel knob and let go, the wheel does a full stop. No free rolling for a bit, just stop.
So I reconnected the remote and it went back to normal
Went outside, on the board and started going. 20 seconds later the remote control started vibrating 2 or 3 times and I lost braking control. Looked at it and it said something like “voltage low” and a split-second later switched to “disconnected”. I almost missed the actual error message.
I managed to foot-brake, inspected the board and the battery was off. Didn’t turn on anymore.
I removed it and slide it back in. Now when I click the power button it just flashes blue rapidly.
I thought this was the battery low warning that people here mentioned, but the battery was still 60% full earlier the day so this can’t be it.
So wtf is going on?
I tried charging the battery a bit and put it back into the board but it still flashes blue so I guess the battery is dead. I have a second SR one and am sure revel is gonna help me out but I am a bit sad that this happened with less than 10 times usage.
I am also worried of sliding my SR battery in with the fear that it fries too.
I managed to get a video of the swapped wheels in and it still wobbles so I’m guessing the left motor has an issue. I’ll swap the adapters next but now I’m a bit scared of this happening again while I’m on higher speeds. Suddenly without brakes is scary and I’m glad I practiced foot-braking with this deck before I converted it into eskate.
I’ll contact Revel and see what they say.
/ EDIT: I inserted the SR battery and… it still flashes blue. So I guess not the battery is fried but my entire kit. Any ideas?
/ EDIT: after talking with the CS, the rapidly flashing light means it’s in pairing mode. Repair the remote by holding the powerbutton when it’s off to fix
So time to put together an email to Flo together with some video of what is happening including the power problems in your last post. I’m sure Flo will take care of you. One thing that might help flo to diagnose this would be to take some voltage readings of the two batteries. The way I do this is to turn the battery upside down and rest two knife blades into the two terminal slots that are furthest apart. then I touch the volt meter to the knife blades. This should tell Flo if you have issues with both of your batteries or if the problem not battery realated.
Thanks @BillGordon, Hi Paul, thanks for your response!
then I think i will stay with the front surf adapter only, i will not mess with the rear one in the revel kit, altough still i would need to place a raiser there.
i also want to say that i’ve learned a lot about electric skateboars from your comments an videos Paul, so thanks so much!
Happy to help. Just be very careful putting an agressive steering mechanism on the front of a board that can travel at the speeds that a Revel kit is capable of. If the waterborn adapters are alot different than double kingpins, you might be fine. If for example you have travelled down hill at 35MPH on a waterborn adapter with no wobbles, then maybe speed wobbles won’t be a problem. Let us know how it turns out.
Paul i understand your concerns and i appreciate it.
Surfskates are intended for real surf training/simulation, not for high speeds. also fun and nice to do some sport while traveling short distances but sometimes you get tired, or cant pump certain streets because of crappy roads, or maybe you need some extra power to climb hilly streets.
In my case, I wont be trying to win monaco grand prix, just trying to be always on the wave, that is maybe speed 1 or 2 on the revel. so high speeds wobbles shouldnt be a problem (for me)
best regards!
Yep, already reached out.
I’ll update if anything new happens but I’m guessing I’ll have to wait for a warranty replacement (if I’m eligible) which will take another 2 months like my first kit, so I’ll be signing off this thread until then.
Sad that I was only able to use it for less than a week in total. Not sure what went wrong and what broke my kit in the end but these things happen and I’m not angry. Despite having issues from literally day 2 of using it, I am still very positive towards revel. The experience while it lasted was fantastic.
Now just hoping I’ll be able to get a working setup before summer hits. I cancelled a different board order after the revel arrived that would have arrived next week but oh well.
where do you live?
Towards me? Japan
The problem is the huge delay because of corona. The website states 3 weeks for new orders but in reality that’s longer
