That is one killer build! Looks totally dialed in as well, a bike to ride!

Most of you that have been into ebikes for awhile will know of Luke's exploits on Endless Sphere, with his deathbikes and all the crazy battery experiments he did for us early on and eventually also went to work for Zero Motorcycles. We all learned a great deal from him... Well he and a...

The Sutra is not a bad bike, but it's not an ebike; if you're looking for a Bafang conversion project just shop bikes direct and go from there for best bang for the buck, imo. I personally ordered the Current because I wanted to try frame integrated motor/battery components, torque sensing...

Yeah the marks on the handlebar are only relevant for reference or repeatability, as the headtube rake and stem angle all changes the actual ground reference relative to the little degrees markings. Level bars is the correct way, but there are no proctored bike exams so you can do what you like...

The 1,000km Prologue "warmup" leg starts 1 June 2021. And here's a general presentation on the event: General Presentation The adventure rules: Adventure Rules Finally, the technical rules: Technical Rules To get a taste of what's to come, there's a 1 hr. docu about the 2018 France to China...

I hear you on that back rack weight, I had on some of my first bikes a large 52v 22ah brick battery in a rack bag, and it was a pig handling! Your work on the fork mounted battery makes really good sense to me, I've felt the same way on where to position the load on everything from road bikes...

Totally understandable, solar is the more energy dense option in the summer (lighter than batteries per wh/day), and is preferred in a actually unsupported ebike trip where they use solar canopies and things on the bikes like for trips across the Aussie outback (no other charging sources...

I've not tried it, but these might not be too hot in the summer, they look thinner and light. I was searching for this type for you because my wife has a set of springy muffs similar to this that the loop goes behind the head like this, but they are thicker, really more for winter. These type...

100+30 could be nice, depending on how you like your reach already on the frame. It should put you more upright. I'm running mine in the most upright config now, with the stem above all three spacers, but I don't have enough saddle time on it yet to know if I want to experiment any more with...

So Origami Bicycles makes these really cool analog folding bike kits that come shipped in a normal checked baggage luggage suitcase, and inside the luggage is a trailer kit to turn the suitcase into a bike trailer, along with these highly functional 20" bikes for road touring. We got them for...

Couldn't you just sell it into the normal dirt bike ORV market that already exists for this size/power and add a MCO/title and the motorcycle VIN, lights and safety features to make it a "mini dual sport" so the owners could register it in any state right now if they wanted to? MCO and VIN...

Wouldn't a federal NHTSA definition just be a carbon copy of the motorcycle regs but just add a hp limit to the definition, like 1-3hp? What mandatory safety features would be worth leaving off to save a few bucks on a smaller engine motorcycle or scooter? If a manufacturer isn't driving the...

I don't see any reason why >1hp road motorcylces or scooters would need another class just to avoid a two day safety course or a basic license test requirement. If the other big *49cc scooter manufacturers thought it was a problem, they'd probably have proposed it already. I think Honda...

Oooh I gotcha. 49cc would be above the 1hp/750w limit and motorized bicycles were already a federal/state legal thing before ebikes existed en masse. The original intent of the old motorized bicycle laws which afaik the CPSC and first ebike laws sprang from was having a motor that has the same...

That's not niche though, that's a category that has existed since well before I've been alive at least. Kids usually start out on dirtbikes and ATV's in that multi-HP power class from ages 7-8 on up. So for the offroad thing, I think it's covered fully too, there is already consumer safety and...

Beyond the HMI interface issue with the microcontroller for sub-750w bikes (throttle vs. pedal sensors), I don't get why they current motorcycle regulations aren't good enough for the >1hp bikes. You can just title it or issue a MCO for a motorcycle as a manufacturer for anything with greater...

Hey, another thing for your tour if you're interested in solar, Grin has a new source and is once again stocking the fully adjustable boost MPPT solar charge controllers that can charge higher voltage ebike batteries from a low volt flexible/travel solar panels. They are nicer than the Genasun...

Yup, almost all enforcement is a loser, basically. Trail users are going to use the trails as they see fit, just as average road users go the design speed of roadways and not what the numbers say on the speed signs, and the only way you'll change behavior is through lobbying the trail users...

Heh, yes very true, it's all very dependent on jurisdiction. Where I just moved from, real speed tickets were moving violations and *camera* speeding tickets were just administrative "fines" with no points and not much if any legal standing, which you could pay if you wanted to, or if you...

I think the one thing to remember is that class, 1, 2, and 3 all have the same legal power limits, all go uphill at the same speed assuming the manufacturer is using the full 750w, and will all do the same exact amount of trail damage because the physical torque potential is exactly the same...
