Geared v.s. Direct Drive eBike motors
We often get asked  what is the difference between geared motors and direct drive motors? From the outside of a motor, you can’t see much difference between the two, however inside there is a huge difference. Geared motors Geared motors have an epicyclic gearbox inside the motor casing, which has an outer gear with inner teeth which connects to the wheel, 3 planetery gears, and then an inner gear connected to the motor itself. It looks like the photo above. The reason for making a motor like this is that... Read more...
My motor doesn’t fit!
This is the most common problem that we find with eBike customers – the motor wheel doesn’t fit into the front forks Sadly, even though this is a common problem, few eBike motor wheels will fit into every bike fork. There is a certain amount of space that is required to fit all of the bits that you need for a motor. The magnets, coils, gears, casing etc. all take up room. So even with the most compact motors its common for the motor casing to end up rubbing on... Read more...
What is a hall sensor and why do electric bike motors need them?
Hall sensors are in most eBike motors, but not all. Ever heard of them and wondered what they are? They are magnetic sensors which help the controller to know what the position the motor is in as it turns, so that it can keep it turning. Read further for some more detailed info and photos. Most eBike motors have “hall sensors” which help the controller to drive the motor. In another post here we will talk about the practical aspects of motor control and hall sensors. But first, for those of you... Read more...
Recipe for a Badass DIY Electric Mountain Bike
By this point, we already know that bikes are awesome and good for you, cars are useful for a few limited things but come with major disadvantages, and electric bikes combine most of the advantages of both. But they do still come with the downside of, “how does a somewhat experienced cyclist get a really good, fast one without spending several thousand dollars?” I’ve made two attempts at the problem so far, with the following two bikes in my little test fleet right now: I started with a home-brewed conversion of an existing commuter bike, putting it...

Turn Your Bike into an Electric Bike with a Conversion Kit
You’ve probably seen electric bikes whisking thrill-seekers along a dirt trail or carrying tourists on a tour. They look fun but make no mistake, these bikes can be expensive. They can also be too heavy to use manually when you don’t feel like an electric-powered ride.    These two factors make an electric bike conversion kit a happy medium. You can use your regular ride, but with an added boost when you want it—and save thousands of dollars! Electric bike conversion kits also give you flexibility—once you’ve satisfied your need...

The Science of Energy: How E-Bike Batteries Work
If just 22% of urban passengers worldwide used e-bikes, emissions would be reduced 47%. That saves $128 trillion when compared to how we travel today, not to mention the positive effect on the environment. In a world where burning fossil fuels impacts climate change, e-bikes offer an environmentally-friendly and economical mode of transport. E-bikes are changing the transportation game for cycling enthusiasts, but their maintenance takes a little more know-how than your traditional bicycle. Whether you bought your e-bike already assembled or converted your everyday bicycle, one of the most important parts of... Read more...
Electric Bike Kit Guide: Make Your Current Bike More Fun!
Electric bike kits are a solution that allow you to add a motor, battery and electric controls to a non electric bike to make it into an e-bike. Chosen with care and installed correctly, the resulting e-bike lets you ride with electric assist just like a ‘regular’ e-bike. With the evergrowing range of readymade e-bike designs larger than ever, kits have some competition from off-the-peg, ready to pedal e-bikes. However, they still offer positive advantages as well as some drawbacks which are considered first-off. Pros You Like Your Current Bike: You... Read more...

Types of Electric Motors for Electric Bikes
anuary 21, 2016 by Average Joe Cyclist 2 Comments  Thinking of buying an electric bike? Great idea – but spend some time thinking about what type of electric motor you want for your electric bike.

Hub Motor vs Crank Drive Motor – Which is Better for an Electric Bike?
January 25, 2016 by Average Joe Cyclist Leave a Comment Most electric bikes have a motor on the hub or on the crank drive. The vast majority of electric bikes have hub drive motors. However, crank drive motors are readily available on many electric bikes, if you want one. Deciding which to choose is tricky, as both have advantages and disadvantages. The best advice is to be very clear on the pros and cons of each motor, and then decide which works best for your own needs.It is not easy to decide whether to... Read more...
Heavy-Weight Senior Builds His Own Ebike!
July 4, 2017 by Average Joe Cyclist 2 Comments This is a guest post from 70-year-old Bob Seible, who decided to build an electric bike that would be tough enough to meet his needs. As I have written in my Guide for Fat Cyclists, most bikes are only intended for people up to about 220 pounds. Bob is in a higher weight class that that, so he wanted a good, strong bike – and he wanted it to be electric as well. Also, he was working to a pretty tight budget. So, this is... Read more...
Origin 8 Crawler With Nuvinci Hub As A Possible BBS02 Donor Bike For The Criminally Insane
Karl Gesslein / April 1, 2015 Origin 8 Crawler with a nuvinci CVT hub 42lbs retail at $1500 but going for around $1100 shipped on fleabay. Seems like I’ve been getting a lot of emails about the Origin 8 Crawler fatbike with the Nuvinci hub from people wanting to do BBS02 conversions on it. Seems like a decent platform although pretty hefty at a claimed 42lbs, probably for the smallest frame size. 42lbs is the same weight that my singlespeed Deadeye Monster came in at WITH the motor installed. Add an extended axle BBS02... Read more...
Build An All Wheel Drive Electric Fatbike That Puts Out 1400 Watts Total For ~$1000
Karl Gesslein / February 3, 2015 After making 4 different electric fatbike prototypes out of Bikes Direct aluminum fatbikes I’ve decided to try a different route entirely. The new Storm fatbike is selling their entire fatbike with battery, charger and motor for a measly $499 (till this Friday 2/6/2015). Considering that I usually drop more than that on a motor or battery alone this is a screaming deal that just can’t be ignored. The last time I went shopping for decent 4.9 inch tires they ran about $130 each shipped, and for rims that... Read more...
Sun Kiss – Deadeye Monster DIY BBS02 42lb Single-Track Snow Machine $900 (w/o Batteries)
Karl Gesslein / February 19, 2015 I added a Nexus 3 IGH to this bike after about a year of thrashing on it, and it was worth it. Review is here. I went for a ride on my newest build and was incredibly happy with the results. This is my third BBS02 fatbike conversion and I have to say it is probably the best yet. Although the donor bike is a single-speed Deadeye Monster, I found that with the proper gears in the front and the rear, the motor had enough speed range... Read more...
Walmart Dolomite And A BBS02 Make A Dirt Cheap Commuter That Will Eat Up Hills
Karl Gesslein / February 20, 2015 We’ve been promising this Dolomite/BBS02 build for a while and we’re happy to say it works beautifully. This is one of the least expensive BBS02 builds you can do yourself and without a battery it should set you back ~$700 and weighs in without a battery at 59 lbs. A BBS02 mounted fatbike. Yes please! The Mongoose Dolomite was originally incorrectly advertised on the Walmart site as an ‘Aluminum’ frame but now it correctly says ‘rigid steel’. The website also incorrectly lists the weight at 45...

The Green Machine – DIY Bullseye Monster BBS02 100mm Conversion ~$1750 and 46 lbs (without battery)
Karl Gesslein / March 2, 2015 I built an electric fatbike out of a $499 Bullseye Monster from Bikes Direct several months ago but it took me this long to really get it working right. Initially I had a lot of problems with the drive train skipping and the chain dislodging and getting jammed between the chainwheel and the adapter. After replacing the cassette with a SRAM PG-850 (nickel-plated steel 32-11) and adding a n-gear jump stop chain guide I feel like I finally have a build that is worth duplicating. The finest Single Track\Double Track snow machine... Read more...
The Reaper – AWD Boris X9 DIY BBS02 100mm 12T Mac ~$2200 57 lbs (w/o battery)
Karl Gesslein / March 9, 2015 I’ve built a couple of AWD fatbikes out of my Boris X9 donorbike that I bought for $700 on BikeIsland.com, all have been something of a disappointment. I have to admit that this current build firmly joins my other AWD builds in the ‘disappointing’ category. It is a startling contrast to have a MAC motor and a BBS02 on the same bike with separate throttles and be able to switch back and forth in real-time between the two motors. While the front wheel motor is useful when the bike bogs... Read more...
Duh Banana Bike – Deadeye DIY BBS02 41lb Single Track e-Bike $765 (w/o batt)
Karl Gesslein / June 27, 2015 The cheapest fat-bike build I’ve made and the most fun to ride on dirt single-track The favorite bike of my collection previous to this build was the Sun-Kiss Deadeye Monster that I built specifically for single-track snow riding. I wanted to build something a little lighter that would be dedicated to single-track dirt and mud and not so much for snow. What I ended up with has quickly become the favorite trail bike in my 6 electric fat-bike fleet. It is a cheap and easy build that can be... Read more...
Dark Matter – Bullseye Monster Pro DIY Biktrix BBS02 46lb Single Track e-bike $2049 w/ out Battery
Karl Gesslein / August 5, 2015 Dark Matter – this Bluto BBS02 build provides the ultimate street legal trail-riding experience I have been procrastinating for months about buying a Bluto Front suspension fatbike to convert. When I finally broke down and did this build the results were astounding. The biggest problem I have found with the Bluto fork (review here) is how hard it is to go back to all my other rigid framed bikes for trail-riding after several weeks of riding Dark Matter.   When riding on snow you can carve up the trails...

Orange Crush – Cheapo Commuter BBS02 750W 8 speed e-bike ~$780 45lbs w/ out Battery
Karl Gesslein / November 6, 2015 I wanted to build a gas car replacement for my 17 miles each way commute into town. After not a lot of deliberation, I settled on the Haymaker 1500 from Bikes Direct which was the least expensive (<$300 shipped) aluminum framed bike with a decent shock I could find. I didn’t do a lot of upgrades to the bike other than adding a rear rack and bag for holding my larger 25Ah batteries as well as adding a cheap ebay kickstand. I swapped the front brake with an Avid... Read more...
My Little Bronie – Sette Ace Single Track Full Susp DIY BBS02 750W 9 speed ebike 40lbs ~$1500 w/out battery
Karl Gesslein / November 7, 2015 Is this nut job of a blogger really starting a build thread for an ebike he calls “My Little Bronie”? You bet your sweet ass I am. This was the bike that started my love of singletrack riding 15 years ago. It was also the first e-bike that I ever built that wasn’t a total piece of crap. There were other DD & geared hub builds that I had done, but none of them felt the way that I thought an electric singletrack trail bike SHOULD feel. “My Little Bronie” forever changed the...

Death Trap 2000 – Road Bike DIY BBSHD 8 speed e-bike $1200 36lbs w/ out Battery
Karl Gesslein / November 5, 2015 I realize that nothing is farther from a real fat-bike than my Death Trap 2000 build, but bear with me. About 8 years ago I thought I would buy some spandex grab some power bars and join the road-biking crowd (Insert gratuitous epic rap battle link here). I ended up buying a Dawes 1500 from Bike Island with a replacement carbon front fork for only $400 (they usually go for $550). Unfortudently I found out that I totally hated road biking and my ass looked fat in spandex, so the... Read more...
Phat Phuk : FB 5 2.0 Snowshoe 2XL DIY BBSHD 1000W 10 Speed ebike 51lbs ~$1850 w/ out battery
Karl Gesslein / November 11, 2015 There’s fat bikes and then there is the “what the hell is that?” bikes. The Phat Phuk really deserves a category of its own as the massive 5 inch actual width tires are like nothing else currently on the market. Vee Rubber decided to release a tire so big that it won’t even fit on almost every factory fat bike in production. What a great idea. If you build it, they will come Massive 5.05″ actual width tires paired with a 1000W nominal 1500W peak electric motor makes the ultimate... Read more...
This Is Why They Hate Us : BBSHD 1000W Singletrack Testing
was underwhelmed with the street performance on my Death Trap 2000 road bike build with the BBSHD. The next build I did was my insanely obese tired Phat Phuk which was perfectly representative of America’s Fat Epidemic. The Phat Phuk did remarkably well even with the bad joke that is the 46T steel chainring that Bafang ships with it (don’t worry better chainrings and adapters are on the way). The large wheel diameter of a fat bike and a monster 46T chain wheel assures that you’re always riding in the woods on your main granny gear or one gear... Read more...
Phatter Phukker : Snowshoe 2XL Steel Lurch DIY BBSHD 10 Sp Ebike 55lbs ~$1780 w/ out battery
Karl Gesslein / November 17, 2018 I broke the frame while thrashing hard on my Aluminum framed Phat Phuk last year so I decided it was probably time to switch to steel. There are several steel framed fatbikes that will fit the 5.05″ SnowShoe 2XL, but the one that I could find the cheapest was a Bikes Direct Lurch NOT currently available for $1099 here. I got mine from Bikeisland.com last year for a mere $750 shipped with some scuff marks and a missing front fork. I got a bunch of take-off front forks from Lunacycle for about... Read more...
Upgrading And Modding The Sondors Electric Fatbike On A Shoestring Budget
Karl Gesslein / February 11, 2015 So you plunked down your cash for a chance to get your hands on the Storm Electric Fatbike from the Indiegogo campaign. I would start budgeting you money for upgrades now, because I can guarantee you will want to upgrade this bike in pretty short order. The bike is pretty heavy and the motor and battery are pretty small. Storm Ebike – A dirt cheap platform ripe for upgrades UpdateL Lunacycle.com has created a huge area on their website for tons of upgrades for the Sondor’s ebike that... Read more...
You Can Have It All – Power & Speed : Nexus 3 IGH Paired With A BBS02
Karl Gesslein / November 20, 2015 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 periods without any real problems or failures. The most critical thing that I found is to make sure you’re not running too much power and load on them at the same time... Read more...
Converting Bikes Direct Fatbikes To Singletrack eMachines
Karl Gesslein / February 21, 2015 Several months ago I started looking seriously at creating ‘the ultimate fatbike’. I knew it had to be 2 Wheel Drive and I knew it had to be full suspension, but I had no idea where to start. Once I saw the Quigley Full suspension fatbike from Bikes Direct I fell in love. With a high-end component level the Quigly looks perfect for electricfication Before Doug’s 100mm axle conversion for the BBS02 had even come out, I was planning on mounting a BBS02 on this bike even if I had...

How Much Power Really Is Enough For Your Build?
Karl Gesslein / September 9, 2015 When planning and designing an ebike build one of the first questions that a builder needs to ask themselves is how much power do they really need?  A perfect build would have enough power to get up the biggest hill in your commute at the speed you want to go uphill at and would also have the top speed that you want to ride at available when you want it on the flats. Building a bike with more power than you need means you have to... Read more...
Direct Drive, Geared Hub or Mid Drive?
One of the hardest questions most builders have to ask themselves is which direction should their builds go in. Fat bikes are particularly difficult as a 26″ rim with a 4″ fat tire ends up being a larger Diameter than a 29er tire. This larger diameter means higher top speeds and lower torque no matter what motor/gearing combo you use. The problem with fat bikes is that they are a terrible design for high speeds. Running low pressure tires and tubes creates a lot of friction at high speeds that... Read more...
How To Buy Your First Ebike Or Ebike Kit And Not Get Punked
Karl Gesslein / March 5, 2016 This article has been swimming around in the back of my head for a while now. Since I am over $20,000 into the sport, and since I have spent the better part of my life being a Rock Punker I feel like I am probably the best-qualified person to write it. Most people’s experiences with e-bikes goes something like this. They discover Endless-Sphere and spend a bunch of time reading articles, then they look at people out there selling ebike kits and they decide to buy... Read more...
It’s My Mid-Drive And I’ll Fry If I Want To : The BBS02, BBSHD & Cyclone Shopping Guide
Karl Gesslein / February 19, 2016 Several times a week I get asked the same question over and over by loyal readers just like you. What mid-drive should I buy? Although it seems like a simple question, getting the right motor for your application can be a daunting task for the uninitiated. This article will help future mid-drive buyers make an intelligent and informed decision that will bring you years of fun and enjoyment. BBS02 750? BBSHD 1000W? Cyclone 3000W? Decisions, Decisions.

The Dark Side – DIY Cyclone 3000W Nuvinci N171 Deadeye Monster ~$889 57lbs w/ out battery
Karl Gesslein / February 25, 2016 “Young fool. Only now, at the end, do you understand. Your feeble skills are no match for the power of the dark side. You have paid the price for your lack of vision.”  – Emperor Palpatine I wanted to do a mid drive build that would be dirt cheap and still work equally well both on single track and on the road as a commuter. In the end, I created a monster that performs well in both arenas, but is the master of none. The old school nuvinci... Read more...
Because You Need To Start Exercising More Than Just Your Thumb : Bafang 1000W Max Ultra Torque Sensing Mid Drive
Karl Gesslein / March 19, 2017 Although last time I was in LA I swore I was never ever going back, here I am again at the Lunacycle HQ spending several hours a day sitting in traffic. How do people live like this? No wonder ebikes are so popular here in Southern California. People can get an ebike and commute on the bike paths along the ocean and avoid the traffic completely. If I lived here I’m sure I would do the same. I got my hands on one of the first prototype... Read more...
Choppy Shloppy : Build Your Own Ultra Max Specific Frame And Get Riding Already
Karl Gesslein / March 3, 2018 The Ultra Max Ludicrous edition (2500W peak) fitted onto a modified FS fatty frame One of my pet peeves about the new torque-sensing 1000W Ultra Max drive unit is that there just aren’t that many frames for it available in the states. The original Bafang Max drive which only sported 350W of power has a totally different mounting bracket than the Ultra Max which means you just can’t fit a round drive unit into a square hole. While there are prebuilt ebikes on the market that you can... Read more...
I Void Warranties : Hacking The Bafang Ultra Max Mid-Drive Ebike Drive
Karl Gesslein / November 23, 2017 There is half a dozen low power torque sensing mid drives on the market right now that advertise themselves as being between 250 and 750 Watts. The one thing that all these ‘low power’ drive units have in common is that there is absolutely no way to program the drive unit to do anything much other than what it is set to do from the factory. The most frustrating part is that often they have built-in speed limiters that you have to install special defeat-devices to overcome.... Read more...
How To Reprogram Your BBS02\BBSHD So You Can Use Pedal Assist On SingleTrack Without Getting Killed
Karl Gesslein / January 15, 2016 Ever since I got my first BBS02 2 years ago I pretty much gave up on pedal assist for anything except riding on the road. The stock programming on the BBS02 from the factory is absolute crap and it takes a lot of pedal movement to get the PAS system to activate and then after you stop pedaling the motor keeps running for up to 25 feet depending on your current speed. Can you imagine going full-bore in the woods and having a problem so you... Read more...
