Re: PaulD's lightweight mid drive development

1) It is too bad that Sempu etc. don't make an ISIS type bb. I have pretty much promised myself that I won't buy another bike without that interface, it is just plain superior to the tapered spindle and way more crank options out today. Searching images on the web turned up an ISIS version of the S...

Re: Full suspension mountain bike Friction Drive

Well the toothed roller was big fail. Sounded like a jet taking off. Back to previous setup for now (which works beautifully) and back to the drawing board. Just an idea Kep, how about cutting out a section of knobby tread with some scissors and bonding it to the motor. Imagine it'd still make a bi...

Hi Brian, For $5250aus on sale with Fox 36, code r brakes , GX 12spd etc etc It was hard to pass up. I was planning on another build or purchasing a surron. I’m really liking The Yamaha unit, pulls hard for what it is and the speed limiter is hacked for free which is the first modification I did :)...

HI VasiliSk,

does your controller support regen switching to active braking at low speed?

thanks

Re: Norco Sight VLT 2 first impressions

thanks for your review. My goal is a multi kw bike that handles like a factory pas bike. Have you tried a bbhd, mini cyclone, etc...?I demo'd a spitzing, it was fantastic I like the sound of that, my search for that right balance of bike and ebike still continues. Sub 25kg and about 2kw with loads ...

Norco Sight VLT 2 first impressions

With the recent spate of factory e-mtbs hitting the market and the steady improvement in drive systems and higher capacity batteries, the urge to see for myself first hand how a factory ebike compares to the various DIY builds I've done over the years, became too great and I purchased a Norco Sight ...

Hi Bob, Couple pics of the bike and HXR yeti2.jpg yeti1.jpg I got the crankset from Chain reaction cycles online from Ireland.

I have used dynamat in my van to reduce cabin noise. Its quite heavy but it does work.
You'd only need a little bit to deaden the resonance, versus the layer of sound deadening in your van. It might only dull the frequency a bit but might make the ride a little more pleasant

It's the vibration through the frame that needs dampening.
Dynamat might be worth a go to damp the resonance

Re: My RC Mid Drive with Single Stage Reduction

Hey Bob, very impressed with what you've done with drive, so much so I'm going to convert my Yeti SB5.5. I've just placed the sprocket order with the lovely ladies at Rebelgear. Only change from your design is I'll mount the motor on a plate from the ISCG mount and being running a HXR Easy Shift fre...

Re: Lace 32H rim with 36H hub motor

All things considered, yeah it was easier. I had the 32h rim and the only rims I could find at the time were well over $100 shipped compared to the rim I had on hand. Re-drilling the spoke flange only took about half an hour.

Re: Lace 32H rim with 36H hub motor

I've redrilled the spoke flange on a bafang bpm to be a paired 32h single cross. It was quite easy to do with just a ruler, a marker, a centre punch and hand drill.

All the spokes are the same length and had no problems truing or with spoke tension.

Great video CD, you're getting quick at editing :shock:

Some sharp rocks poking out of the ground around 9lives place.

Gaadi double ended tube saved the day (I've ordered one as a backup when patches just wont stick) kind of tough to get the cro out the Keewee without a socket and bar.

Re: Trial riders need their clutch?

but the torque was not enough he said. Because of the "spin up time", comparing electrical motors to turbo chargers this sounds like the controller is stangling phase amps too much, Adaptto controllers and many other controller tend to do that. The old style EB3 infineon controller suffer much less...

Great looking bike 12-C, 30lb (13kg) in the backpack must be a little uncomfortable :shock: but I'm guessing that's just temporary until you get something slightly more compact

Re: PaulD's lightweight mid drive development

thanks Paul, of course, I didn't think that through :? Rocky Mountains drive is interested, could lend itself to a kit option, but would probably need a lot of reduction at the planetary to bring the rpm down http://14761-presscdn-0-15.pagely.netdna-cdn.com/wp-content/uploads/sites/2/2017/05/Rocky-M...

Re: PaulD's lightweight mid drive development

A freewheel is a significant engineering effort Hi Paul, very elegant design, I think it'd go great on my Yeti SB5.5. Regarding a freewheel, since you're going PAS only, could you not bypass having a freewheel altogether. A torque sensor could be added to the lower/return side of the #25 chain wher...

Re: DH dual motor = LR mid drive + Grin all-axle front hub

Hey John, good to see you've sorted most of the reliability issues with the LR big block. Too bad the frame isn't holding up as well. Maybe time to transfer the LR over and other parts over to a new frame. A Quilbix Q76R might be a good mid drive candidate. The Cyclones your vid looked to cope well ...

Re: Wheel popping ability in a BPM

You can wheelie a pedal only bike even if it's e-bike weight. It's all technique. 200W is plenty if your pedals work too. power wheelies are much more fun though :D simplest route would be a big DD hub and dial up the amps. Granted unsprung weight isn't ideal, but on a long travel DH bike, with the...
