I’ve been insanely busy lately and completely neglecting this blog. The nice folks at Carson Rental loaned me a $120,000 30,000lb bulldozer for a week without ever asking me if I had ever driven a bulldozer (I hadn’t). I proceeded to spend a week tearing up my property with 14 new ponds and many acres…
High power mid drives ebikes are great, in fact I believe that at power levels less than 4000W there is nothing else out there that can compete with a mid drive ebike. When running a ‘low power’ mid drive like the BBS02 that peaks out at about 1300W you can get away with using almost any nickel-plated…
One of the biggest problems with running a mid-drive motor is that you end up having to throw away your front derailleur and gearset. This means you have to settle for whatever gear range you end up getting from your cassette. Most cassettes go from an 11T to 32T (for a 21 tooth ‘range’) which…
I’ve been pretty bullish on the Nexus-3 IGH for fat bike builds the last couple of months. The Nexus-3 IGH only adds a little over a pound to the weight of your ebike, but it drastically increases the usable range of your BBS02 or BBSHD motor over a single speed setup. It seems to be…
NuVinci built this really cool CVT in 2015 called the N380 which they say can take a whopping 350 Watts of power (as long as it’s not a cargo bike, then you can only get a measly 250W). I’m not going to waste your time telling you about how this thing works except to say…
In the past, I’ve told people when they replace the nylon gear (instructions are here) to use heavy axle grease on it as the Lithium grease that it ships with is incredibly light and tends to just spin-off the primary reduction gears when they are spinning at around thousands of RPM. After 5 minutes of…
I have spent a lot of time researching IGH on the Internet to try to figure out which one can take the most abuse. Time and again the hub that people mentioned as the toughest was the Nexus 3. There are people who claim to have run several thousand watts through these hubs for sustained…
Two BBSHDs are on their way to my house in the NY boonies from China by airmail. I’m left to ponder how much awesome it’s going to be to be the first person in the US with a production (not prototype) BBSHD mounted on a fat bike. I also know how much their 558g 46T…
In so many ways Bafang’s BBS02 750W drive unit is a dream come true. Almost anyone with very little technical know how can order a drive kit and 48v-52v battery pack and have it installed and running on almost any bike with 2-3 hours of work. Any other mid-drive ebike kit is going to take a…
I’ve looked at a whole lot of fatbikes for sale in the US and one thing I’ve never seen is a Bluto equipped single speed fatbike. Many newer fatbikes are shipping with a bluto ready tapered headtube which seems to be the emerging standard for fatbike frames. For older frames you might be able to…
