    TCMB 3D Printed Parts

    Have you considered having it machined out of delrin or nylon rather than printing it? The grain boundary planes in an FDM or SLS part are a high risk for fracture propagation without annealing/thermal stress relief. If you are going to keep printing it, get fancy with it! Complexity is free...

    Sold 2018 Alta Redshift SM | SF Bay Area

    Great bike, I love the attention to detail. I'm in the middle of a move and shuffling bikes around, but if you still have it in February, let me know.

    Duromax XP4850EH Hybrid Generator on sale for $254 shipped

    Oh really? Is that to say we finally get to know the handshake/charge protocol for the Alta on-board plug? That would be the missing link to let us build homebrew powerwall charging setups. Stuff some saddle bags or panniers full of 18650's and go on a bike-venture! If only it was that easy...

    Duromax XP4850EH Hybrid Generator on sale for $254 shipped

    Pretty sweet looking generator, do you have this specific one? Looks pretty loud... Does your kick back code work for higher output models? Some of us are looking to run tire warmers too :)

    Bad news for aftermarket? The battery management tech.

    I wonder if you could link the map (and thus active cell architecture) to throttle position. Something like Map 1 (max range/thermal control) for anything under 50% throttle, and then dump all the active cells into series over 50% throttle position. That would give you max range and traction for...

    Snowbike build...?

    From purely an energy perspective, the 5.8 kWh battery holds the equivalent of 22oz of gas (assuming 33.4 kWh per gallon). But that just speaks to the efficiency of the motor, not the real world comparison of fuel consumption. I get about 40 miles out of the 2 gal tank on my yz125, so 1 gallon...

    Snowbike build...?

    Just snooped around in the user manual... looks like it is just the controller and motor. Gotta say, that is a little disappointing. I'm sure it is to save weight, but liquid cooled battery packs have significantly more performance potential than air cooled ones. See Tesla (or any other...

    Snowbike build...?

    Nice! Great to see that it physically works. Temperature control seems to be the name of the game. I'm sure a secondary controller for the coolant motor and some heating coils run off the charging source would solve the charge controller issues :)

    Snowbike build...?

    So I can't get the idea of an Alta (EX) Snowbike out of my head. Seems like a great application... no clutch to worry about and plenty of torque to spin the track. Range would be super low, but you could throw a 1000-2000W generator on the back of the tunnel (or a giant DIY stack of 18650s... I...

    Any sumo racers out there?

    Has anybody raced an SM (or EX/MX/R with 17's) in a supermoto series? If so, how did it go? Any over-heating issues? Larger front disk? Suspension settings? What class did you race in? Talked to my dealer today and it sounds like Warp9 still has hubs in stock and will sell you wheels if you...

    Tax credits?

    Has anyone tried to apply for 2018 Federal Income Tax Credits for buying an Alta? Looks like Form 8936 isn't up for 2018 yet... About Form 8936 | Internal Revenue Service Anybody get any state credits?

    Owner's Review First EX ride! Lots of good, but also some questions.

    I finally picked up a 2018 EX and got it out on some trails! I'm new to California and live pretty much next to LAX, so it's a long drive to any kind of riding that I can find information on. I ended up in the hills above Santa Barbra (Divide peak OHV) because I wanted a view. First...

    240v female to 110v male adapter

    A 5-15P (~$10 at home depot) and an L14-30R (~$40 at home depot... which is too much) and a little 12 gauge or smaller wire should get you going with a hot-hot/hot-neutral setup. I made it out the door for $50 with some free wire for the discard/cut-off bin and it works great. Could probably...
