Re: Definitive Tests on the Heating and Cooling of Hub Motors

Nice work Justin! Yeah I can't disprove what Luke said above and it is entirely possible it was down to the coatings I applied in my cases that caused the FF to be consumed over time. I ended up just adding more to one of those motors so it will be interesting to see how that turns out. :lol: Cheers

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

You know what would be awesome, and maybe since Justin is doing this project it might be possible. If the Cycle Analyst could act as a charge controller. i.e. a plugin unit to the CA that would do the charging (since the CA hardware can't handle much current) that would connect via the CA serial por...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

I've had reasonable success with a this cheap DC-DC converter on my setup.

It might not be the 'most' efficient, but certainly gets the job done at a reasonable cost, size and weight.

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I push my poor little Leaf motor at about 6KW, but I have active fan forced air cooling, Ferro Fluid, and Heat-sinks to shed all the heat when I do crank it up and I do regularly hit 140C before it rapidly cools off. Most of the time it's cruising at 2-3KW though which the cooling can keep up with a...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

C D , looking at the picture of your bike-E it looks like you can use a bigger panel on the front , by making a bracket that extends the lower part of the panel out further and at more of an angle . Also to be able to see above the panel just buy a wind deflector that some motorcycles use on their ...

Hey Lash, Not sure if you saw it previously but I'm running a 60T BCD110 front chainring. I've just got a 14t 5 speed rear freewheel that I will be installing some time soon, so that should give me some decent pedalling speed. There are also some 13t 5 speed freewheels out there, but they are hard t...

Re: My Sun Trip Bike, Back to Back Tandem Trike with Rowing Generator, Pedals, +Solar

Love this project Justin! As one who has done some experimentation with solar on my recumbent, I would suggest putting at least one of the panels in front to break the wind. I found doing this on my BikeE reduced the cruising (~40-50kph) power consumption by about 100W average. I believe it's becaus...

Sweet moves there Rick! Now you just need to mount 2 sub machine guns either side of the frame and you can gun em down Mad Max style. :) I took my dad out for a spin on my Alpha and Fighter today to a local solar farm. Was a blast and the full 13KW+ on tap on the Alpha scared the crap out of my dad....

Re: Definitive Tests on the Heating and Cooling of Hub Motors

I don't know of anyone who has added motor varnish to a sealed motor and then added Statorade. If you try this, you would likely be the first to do so. I actually did this back in June 2016, and I am continuing to experiment doing so. This was the result of my initial attempts: https://endless-sphe...

Re: BMC powered BikeE for Comfort and Range

I was able to keep some wires in the frame by keeping all the battery wires centred along the top. That way, my existing wires could go either side on top of the battery. In my case the humped battery top with smooth PVC heat-shrink and lube made it relatively easy to slide the battery in with the w...

Re: BMC powered BikeE for Comfort and Range

Looking great Alan. Initially I made the hot glue buffer on the top of my pack too tall and it would not fit nicely, then I re-melted it and flattened it down in order to make it fit with room to spare. In the end I managed to keep all my electrical wiring inside the frame still sitting on top of th...

Re: BMC powered BikeE for Comfort and Range

If you've got any space, you should fill it with padding. The biggest concern I still have with my pack is every time I hit a large bump or pot hole and I'm thinking about all those vibrations going straight into my battery. One of the few drawbacks of not having the suspension model of the BikeE. I...

That's quite the rant! I kinda know how you feel, as I had a lot of similar issues with my Fighter when I first got it back in 2011/12. Stealth ended up replacing the whole frame, rear swingarm, seat sub-frame, rear wheel/motor, several batteries (one replacement, 3 repairs), and a bunch of smaller ...

For those with a Fighter who want to know how their 2 speed gear works, have a watch of this.

Thanks for this awesome analysis Justin. This makes me not so bothered that I accidentally put the full 10ml in my MXUS I built recently. I would love to see some destructive testing.

Thanks Jay.

Yeah, that track is one of my all time favourites and one of the best way's of determining if the rebound rate on the rear shock is set correctly. In my case it wasn't and the Alpha was throwing my up like a pogo stick until I slowed it down some. :lol:

Re: Stealth FUTR owners builds and pics

Thanks Lee!

I had not heard that before about the phase wire swapping. When I get around to it I will certainly give that a try.

That Zefal rear mudguard looks good enough and will match the front one also, so might give it a try.
