Re: Best Cushiony Rear Shock for Ebike

And of course that heavy motor on the rear will upset just about any shock/spring combo. Their parameters are set for a bike wheel with maybe 1 kilo of hub weight or less. Put a 7 kilo hub on the wheel and jounce and rebound are not happy campers. Perhaps you can adjust the better shocks and use a m...

Re: portable air compressors for tires

Black and Decker have an inflator also for their "multi tools" (basically a 20 volt lithium drill) for about $25. Prolly not quite as good as the Ryobi but similar and cheaper, particularly if you use their tools anyway.

Re: What lcs display is compatible with my controllers?

KT controllers have the KT and serial number on them. Yours does not seem to have this so I suspect it is not a KT. To connect one of the LCD screens you would need the compatible connector. If you can show the wire connectors that might help.

Re: Using bicycle's frame as heatsink for the Phaserunner

I'm watching this discussion carefully since I have removed the fan from my Wangdd22 booster and will mount it on the trike as soon as temperatures rise. I am hoping to avoid the fan as it is in a bad spot to mount the heatsink correctly against the frame.

Re: KMX Franken Trike 12-18kw Build

Hey AW. You have an auto power transmission U-joint. Much too big and heavy. The one Fechter shows is for steering rods; much lighter and smaller. They make even smaller ones for lawn mowers and 4-wheelers.
Just sayin'.

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

Maybe if we post some pictures it would show the differences. My old foggy memory sort of remembers the 20 amp and 30 amp being somewhat different in structure. However I am still waiting for the weather to get better so I can test the 30 amp one. otherDoc Whoops, we already got pictures of both. It...

The second one finally showed up from China so I paid for it. Banggood was quick with the refund when we thought it got lost in the mail, whic it did. Only 1.33 months to deliver.

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

Well I guess I'll have to join the test group. I have a 36 volt 17 amp controller that has 60 volt caps and 75 volt mosfets so it should be OK for 50 or so volts. I also have a 36 volt battery. As the weather here is terrible (40F and rain) I have to wait a few days until the sun comes out. It alway...

The lack of instructions is simply part of the Chinese plot to rule the world. I will say however that their electronics knowledge and quality has vastly improved over the years.

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

I just got mine and I have a quick question. I know what input and output voltage adjustments are for but it has that 3rd variable resistor that is labeled "CC". Is this for max current ?

Re: Using the Wangdd22 1500W 30A DC Boost Converter on an ebike

I too agree that parallel ones would probably work OK. You are adjusting voltage with the converter, so amps will come from the battery, controller and motor combination. My controller is max of 18 amps, so the watts are limited. My motor draws limited current, so it should not overload anything. My...

Well I broke down and bought the Amazon one. It arrives Friday. If the Banggood one shows up I may have the chance to try parallel boosters, but I really don't see the need. If your fan never goes on in Phoenix, then I don't see the need to parallel. My battery is only 10s5p. In fact I may leiminate...
