Re: Buick Lacrosse 2012 e-assist moto-alternator

There are lots of dyno types; inertial (only mass, but not capable of performing steady tests), water braked, eddy current water cooled, friction dynos, etc. Hi E-vektor, from your posts I read you have experience with dynometers. I'm interested in a DIY solution for an eddy current braked dyno. Ha...

They can build it as an enclosed tamperproof system with good isolation whereas one of us would be risking certain death soldering an 80s lipo pack together on the kitchen table.

Love your work, the blue rearsets look great against the black, you just keep making this thing more awesome. Will you have enough torque to warm the rear tyre with a burnout? Or is that not a problem?

Re: Mid-mount Hubmonster Madass

I realized I couldn't get things to fit right and decided not to hack it up. Instead I built a frame from scratch, though not a MadAss replica. I do have a replica with larger dimensions for batteries in process too, though that's a few weeks away. A testament to your skills when designing a new fr...

Re: Sur-Ron - New Mid drive Bike from China

Linkage actuation depends on suspension travel, the design is primarily influenced by adaptability to meet min and max travel as per design criteria for one frame for steet and off road. Don't think of the 'whishbone'/ linkage as optimal for anything, instead it's to lower production cost first and ...

Re: Sur-Ron - New Mid drive Bike from China

Hi Macribs, that's an interesting question with a couple of answers. An easy explanation is seen in the evolution of motorcycles from unified rear triangle (URT), think twin shock on the swing-arm, to single shock linkage on modern sports bikes. Tuning the linkage offers potential to optomise suspen...

Super cool concept, would you mind taking a picture of the rear shock linkage? SamD has some pretty handy operated cable throttle boxes, not sure if hey use a hall sensor. Can be found in the for sale section.

Re: Liqid cooled hubmotor, >6kW continuous

Really interesting products particularly the battery.
The motor should generate some interest with people seeking higher power. Have you tested the motor in one of your frames? Customers would be interested in the results.

The person who spat at you has emotional problems. He probably deserves pity instead of anger but there is no excuse. Must be a sad existence to resort to assaulting a stranger.

Re: Trial riders need their clutch?

Consider that a clutch enables increasing rpm which riders believe increases gyroscopic action of the engine and resists tilting. A common practice on larger road bikes or sports bikes with tight geometry. I'm skeptical of the benefit for slow speed lower weight applications.

Re: Trial riders need their clutch?

The videos demonstrate the importance of the rider capability versus bike capability. Riders can have multiple bikes for each task but real skill is evident in one rider performing on a single bike.

Re: Kona Coil Air with Magic link.. natural anti squat

Awesome to read a review of the suspension characteristics, IMHO review of squat characteristics is missing from a lot of build reviews. Interesting linkage setup, seems over complicated but I suppose the proof is in the riding. Besides who doesn't love a controllable power wheelie :D
