    HS3540 BOSS BUILD. Now H4065 Boss Build

    I'm curious about your experience with running an HS3540 at 100v. It seems that not many have tried it. Can you tell us more about what it was like?

    Timelapse of my first 100km ride.

    Lots of traffic. Are the cars polite? Did your return trip at 60kph/ 35 mph and 40 Wh per mile include a lot of peddling?

    Elio..... The new Aptera???

    I'd buy one. But there is no way he will make that price. Even on a stripped version with no airbags and a non moveable window. A CBR250R is made in Thailand by the 100,000"s and still costs $4300.

    TYRES !!! ~ Which do you use ?

    Continental has an Ebike specific tire for heavy weight and high speed. The Schwalbe are a little pricey for high mileage use on the rear. . http://www.conti-online.com/generator/www/de/en/continental/bicycle/themes/city/E-Bike-tyres/ECONTACT/econtact_en.html . I would have to see how long they...

    diy tubeless tires for ebike anyone?

    I have been using a DIY tubeless conversion on my mountain bikes with standard tires for years. The Stan's tire valve set up with the tire just seating against the rim was prone to burping. Using a 24" tube for a liner/ valve instead has proven fool proof as the tube and tire bead are bonded...

    Turn key Ebikes

    Sunny and 30F today with the roads clear from snow all the way to the shoulder so I went for a long bike ride. I needed a destination for me and my winter rat so I decided to make the 10 mile trip out to the Kawasaki dealer to drool over the new Ninja300 and talk to the owner about the used...

    Hobby King LiFePo4

    These LiPO are really cheap right now. $0.43 per Wh would rival the best price on raw Amp20 cells at $0.35. . http://www.hobbyking.com/hobbyking/store/__33182__ZIPPY_Compact_5800mAh_8S_25C_Lipo_Pack_USA_Warehouse_.html .

    I like the simple and serviceable clamp build of your battery. It seems like your motor is a bit hungry. 33 Wh/mile for 9 mph?

    DOT approved tires

    The Kenda Kwest is a great deal at $20 for a long wearing, high speed street tire. . http://www.biketiresdirect.com/product/kenda-k193-kwest-tire . They used to make a 26 x 1.95. That thing looks like a scooter tire with 3mm thick tread. . I run all my mountain bikes with standard tires...

    Kona Stinky GM BLT-500 mid drive- frame mounted batteries

    Great build. That motor flys with 74v on it. Did it gain rpm all the way up to 2,300 with the overvoltage? I have a recumbent that I plan to use the BLT-800 with as I have plenty of room under the seat for a long (wide) motor. Thanks for the tip on the Staton-inc site. I was having trouble...

    e-bicycle legal requirements sections ??

    The law is very simple where I live in New York state USA. Electric bikes of any sort are expressly ILLEGAL! Yet NY City is full of them. . Hopefully the new 1000 Watt law that is on the state senate floor will be passed in the next session. . The US government gave 1 billion dollars to help...

    GM BLT-800W bench racing

    This is good news to me. The low rpm that is. I am planning a mid drive conversion for my recumbent. The intermediate shaft rpm will be 343 at 40mph when on the 11t in the rear due to the 13:17 multiplication on the crank side that I need to get the crank back down to 85rpm on the 53t. I could...

    The Mid Drive Hub as a Non Hub Group

    Good to know. If a bicycle powertrain can hold up to operating mid drive for off road, it will easily take anything I would put through it on my commuter bike.

    Back in the Saddle, 'Bent Mid-drive project!!

    I guess it would be pretty easy to knock together a half free wheeling jack shaft out of a bicycle rear wheel hub to mount on the bracket just in front of the mid drive motor. This would let the pedals freewheel and I could then play with the in and out gears to get the motor at 1000 rpm while...

    The "Elf" Velomobile (new video)

    A brave attempt. He has a lot of money tied up in the design. It's a bit wide. Eventually people will have to get used to the idea of sharing the road with such vehicles. If it could go 40 mph it wouldn't be in the way on a street.

    Back in the Saddle, 'Bent Mid-drive project!!

    That is a photo of a Goal although I actually have the rear suspended 26" high racer and have a front fork that should fit the head tube to suspend the front. The rear is 9 speed with an XT derailleur. Pro bike racers can average 450 Watts for an hour and sprint at 1500 watts for 90 seconds...

    Back in the Saddle, 'Bent Mid-drive project!!

    Great thread. I have a Performer dual suspended 26" recumbent to build as an electric commuter and am weighing the options of a Clyte 3540 rear vs mid drive. I have an idler midway back already so this would seem a good place to mount a motor. The rear suspension would work better without the...

    High power RC motor and drive unit production

    Could your kit work for me to convert my Performer high racer 26". I am thinking mid drive is quite convenient for a recumbent since I have an idler pulley right in the middle already.
