Re: Mk. 4.5, the better E-Tard

It's sad to see the other frame cut up but guess it's all in the name of progress. I am really looking forward to watching this build. I love the idea of the swing-arm pivot being the motor since it really simplifies the chain tension situation. Your packaging of the rear suspension looks like a gre...

Swing-arm concept looks great! is that all one piece or 2 halves bolted together? Is it aluminum or steel?

Re: EMC-400 charger setup+Mods

I have an emc-400 related issue I hope one of you charger experts could solve. I bought a used emc-400 that was set for 21s lipo. I figured I could turn the voltage pot down to 82-84v for 20s lipo. Turns out it will not adjust any lower than 87.5 volts. Is there an easy way to get below the minimum ...

Re: Road or Mountain Bike Conversion for Commuter

I also vote for the mountain bike for durability, comfort, and ease of build. Roadbikes are great when you are the power source. They seem to lack comfort and durability in exchange for efficient rider position while pedaling. Under electric power you are going to increase your average speed so all ...

Re: First electric bike journey with the wife.

I have E-biked with the wife a few times. It's really fun. She is full throttle the whole time so it can be a little frightening to watch. I try to keep her on the slower bike with the brighter headlight now that I have seen her ride. I actually just got her bike running with a 12turn 9c motor in a ...

Re: 3000 Watt 72 Volt ? surley to fast at 5400rpm !

40 mph seems perfectly reasonable for 3000 watts. I would think there is a reduction gearbox involved although it is not obvious in the picture. Did you look at the 3rd picture with that "exten tube" on the bottom bracket? :shock: I would stay away from this kit just based on that picture....

Re: Comparison between RC and ebike controllers?

Below are just some observations based on my own experience and things I have read on this forum. I believe the RC controllers are not ideal for smooth mid range power delivery compared to a standard ebike controller. My Lyen 12fet controller is currently programmed for about 3500 watts but it will ...

Re: Dyno Glide - Cruiser Cafe Racer Build - Lots of Pictures

Its hard to say without taking it apart to see exactly what you are cutting into. A less invasive approach to moving the bearing or shortening the whole motor would be to make an end plate shaped like a top hat. This way the bearing stays in the same place on the shaft but the pedals swing past that...

He said a thinner cover with holes in the face would probably work just as well for cooling. I know that doesnt make moddi...

Re: Dyno Glide - Cruiser Cafe Racer Build - Lots of Pictures

If your crank is hitting just the screw on the left you could counterbore the endplate to recess the screw head flush with the plate. The threads would then stick out of the right side and need to be cut flush. That is also assuming the thread on the bolts are long enough inside there. Maybe Neptron...

Re: Dyno Glide - Cruiser Cafe Racer Build - Lots of Pictures

Looks great! Elegantly simple design and it looks right at home on the frame. The chainline may prove to be challenging but from the looks of it you can switch the freewheel to the inside of the bearing plate if need be. How is the pedal clearance with the motor?

Re: Machinist question - How to make a hole

You have a few options. A drill bit that size will want to walk towards the existing hole. You can use a drill bushing to guide the drill bit but those cost money so I will try to give you the basic idea and you may be able to improvise. A drill bushing is a hardened steel or carbide sleeve that has...

Re: Dyno Glide + TransMagnetics 532 eBike Cafe Racer Build

Looks like its coming along nicely. Are you concerned about only mounting to one face of the motor? I am a little paranoid about mine torqueing or spinning the can on the endplates if only mounted on one side. I like that your mount doesn't risk running a bolt into the internal fan like a typical fa...

So I made this thing at work today and it reminds me of a disk brake sprocket adapter like the ones used on non hub bikes to mount sprockets to the ISO brake rotor flange. Its about 14" diameter and 304 stainless steel. Figured that ES members always like looking at machined parts and I thought...
