Thank you for the fork info. I'll contact their international sales offices.

Re: LMX P2 : Freeride trials motorcycle frame development

Are you still using the RST killah? and if yes, what do you think of the quality? I am considering RST Stitch, which are 180mm single crown versions of the same fork, but don't want something crappy

Thanks

Re: 6pence Resistance Spot Welder



I recommend this kit. Postage to Australia was very reasonable. Like $15 or $20.. anyways it's not like it's hundreds....

Good luck

Re: FREY eMTB with Bafang m600 is developing with your ideas!

the big issue here is cost... sure you can develop something fully integrated but it costs more, and therefore you've lost a large chunk of customers. There are two types customers - those who want a stealth ebike who will pay a lot (aka they will buy a Specialised or a focus or german / French bike...

Re: FREY eMTB with Bafang m600 is developing with your ideas!

so does that mean you want a internal battery or get them to build a frame with a flat down tube that will accept any aftermarket battery?

Re: Another SMD lebowski PCB

Nice one, looking forward to pics. I use a Stereo microscope for soldering, but all work is done by hand even down to 0603 components. The TQFP44 chip is not hard to solder by hand, use lots of flux, and a solder blob that is about 3 pins wide, then just run the iron from one side to the other, by t...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

For torque based pedelec having the e-brake cutoff is not an absolute necessity. It's not a typical riding technique to use the brakes while pedalling under power. Sometimes you tap the brakes mid-corner for stability, and in these situations, the delay caused by the e-brake cutoff causes control is...

Re: build your very own Lebowski controller !

Don't do it. Buy genuine from Digi-Key or element 14, Farnell etc. I bought China ones and they made the controller ring, and not perform correctly.

Re: FREY eMTB with Bafang m600 is developing with your ideas!

What do you mean by open system? If you mean that you have the choice to build you own battery, well those 'external' battery packs are no different to an internal battery, they are still custom designed specifically for that frame/brand. External or internal I don't really care. Internal seems to b...

Re: FREY eMTB with Bafang m600 is developing with your ideas!

Frey: what do you plan to do about the internal battery? or are you planning to make it an external battery? If it is internal, what battery pack / housing are you planning on using? is there a modular case available that will fit inside a frame? If yes, can you offer a link please? Thanks Andy Oudyn

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

I was thinking exactly like that with press pins for the bottom (power board) but then the top (CPU board) would have edge clips that hold onto the sides of the PCB. Because there are no holes in the CPU board..

Re: Power PCB for Lebowski Controller to be combined with Bobc's processor board

If you move the tracks and make yourself some mounting holes, we could use some 3d printed PCB clips that holds the edges of the CPU board. And then a touch of silicon to hold it.

I can model some clips of you give me the board spacing, PCB thickness and hole size.

Ok good to know... I was under the impression that noise / interference would be a problem as well. So conceptually, If I keep the gate signal closely coupled with its reference (either GND for low side and phase-out for high side) by having the reference immediately below, and possibly beside as we...

How does twisted pair compare to shielded cable (like mini coax) ???

Re: FREY eMTB with Bafang m600 is developing with your ideas!

it looks dubious to me. Battery in Pic, but further down the page it has a Hailong Case pictured. Plus I hate it when they get the Part number / specs wrong.

I'll wait until I hear from Bafang or a reputable frame builder that they are available. It's no good to me without a frame anyway

Where is that from?, I've emailed Bafang Directly, as well as Frey and another couple of manufacturers they all say March / April for release. Perhaps this is just a pre-sale?

Bafang like to put their products on the website, but they're not yet available for sale. Best example is the Max Ultra 1000W drive, it seemed to me like it was online for well over a year before anything was available for purchase. Same goes for the M600, it's online already, but you can't buy one....
