    There was something wrong with the egg rider, so I went back to 52 volts. Grabbed a display and when flashing the firmware the bike turned itself off. Yup, I bricked the V2 because I grabbed a new display which all have the auto turn off feature enabled. Marcos talked me through getting it back to life. Is this place cool or what? Hill climbing my ski area today with the tiny 14s2p 40T cells. Made it to the top with 51 volts resting. I do this "hill" all the time and this battery performed way better than I thought it would. Level 8 with the regular Wolf flash, (14s4p of 30Q cells).

    The Nomad is my go to bike for the HD. Craigs list is your friend. The Uzzi's fox 36 is for a 27.5 when the bike new came with a 26. That and slacker dropouts makes this Mullet bike super stable.

    I installed my BBSHD on an '08 Santa Cruz Nomad that has a 160mm coil fork and a DH style coil rear shock. This bike is used solely for mountain biking on trails that have decent technical aspects. The around 50-pound total weight of this bike is not really noticeable on the trail...in fact I'd say it contributes to a beneficial level of increased stability where you don't get knocked off your line as much as a lighter pedal-only bike...much like why a dirt motorcycle is very stable on a trail. My Nomad has a 26" rear wheel and the Fox 36 fork can run a huge 26" tire or a 2.35 27.5 tire. I'm noticing with the pedal assist that the rollover capability is not as big an issue compared to the 29'er because you have more than our wimpy human power, so stalling out on an obstacle isn't as common. I think you'll find better choices in newer frames or complete bikes in the 27.5 or 28'er category for obvious reasons.

    I'm not really having any ground clearance issues on the Nomad. It's only a tiny bit lower than the 42T Luna Eclipse chainring. If I were constantly running in extreme rock gardens or trying to jump up on to sizeable ledges, I think most of these conversions could be problem. However, I measured the ground clearance on our shop's Trek Rail 7 with inside-the-frame Bosch motor, and it was the same clearance as my Nomad. Also someone mentioned the power of the BBSHD perhaps being too much for off road. With the program cable I was able to soften up the power delivery using a lot of good guidance from many of the forums. I like that the controller is noticeably more robust than the BBS02, so you also may have a little more peace of mind.

    Strictly from my opinion and observations so far on the ebike front, I don't think there's much reason to have really light weight framed emtb's because there's not really much of a penalty to have a heavier, burlier framed pedal assist mountain bike. It may actually be a benefit to have the heavier, more competent bike with a motor. On our pedal-only bikes we've all been gram conscious for good reason. This may not be much of an issue anymore...except for lifting the bike onto a rack or such...LOL! I think riding these factory or conversion emtb's is also a little harder on the frame and components because...well...we have more power to plow over trail obstacles and such, so having a little more substantial frame and suspension components is a bit of insurance.

    Version 2 is here! V2 Ludi controller and 72 volt battery. The bike doesn't look pretty as in the last post.

    The only test so far is the dumbest: top speed. It is faster in the same gear, so I am experience the higher voltage increasing motor RPM.

    The controller works fine with my throttle so I don't feel any need to mess with setting I know nothing about.

    I big shout out to Matt Bzura for the battery! Sorry about the installation, I think of velcro as a structural component.

    The rear cassette is an 11spd Shimano 11-46.
    Changed the front out to a Luna Eclipse 42 tooth, primarily to get a more centered chain line.
    In regards to the brakes, I really like the constant feel / modulation of the ICE tech brakes in repeated braking when riding back down the mountain trails .

    Which is bigger, the rear disc or the pie plate you call low gear? 40 tooth chainring? Fins on the disc, I hope they work, my Uzzi is sporting some new ZEE four piston binders. I gotta update. Wolf battery, full bagger, yes panties on a full sus bike. Love how clean your paint is. Battery looks factory,

    Your post on the Intense Uzzi caught my eye . I enjoyed reading about the adventure. I converted an 2002 Intense Uzzi SLX with the Luna bbshd kit. Had to shim it out past the suspension pivot. It's amazing how fun making your own ebike can be, and with what may start as a budget build, well let's just say that one thing Invariably leads to another. It's only running on a 48v shark pack which just barely fits above the down tube. Zip ties are ones best friends in dealing with the harness. Tires are 2.5 x 26 Specialized Butchers front and rear. Chris King hubs and headset , an old 75 mm crank bros dropper post to make starting and stopping just a bit easier. At least pedal strikes don't occur as often as my newer factory made rides , and with about 165mm travel front and rear it makes for a plush old school geometry type ride.

    This might be too much in one's face to be tasteful, even by my standards. The silver one looks better than this white sticker.

    Fox sells decals for the fork so I bought the one called stealth. I have a hub you can't hear and now I have a decal you can't see! The orange was a bit too much, but with the P clamp around it there was too much attention brought to the fender.

    Rear Light, probably a popular Luna light but the first I have gotten and it goes pretty well with the trucker biker theme.

    The wife and I fought over streamers on her bike. She kept saying: "If you like them so much, put them on your bike!" Well, now I have she kind of likes them. Stay tuned to see if I can get them back on her bike.

    Your Paratrooper is a thing of beauty, the Uzzi is more of an abomination of nature you stare at like a car accident. It is also a great place to use up the white zip ties. Must...have...Wolf Battery!
