As the Hub Motor Turns and the LiPo Fire Burns. Two 40 mph electric bicycles on the agenda.
it does not need to be fast right now. it just needs to work. Also I want this one light. My first belt drive. I can order a cheap brushless motor from Hobby King or Alien power. Dan sent me two brushless controllers sitting in a drawer. 15 to 20 mph is fine as I will pedal assist with this bike.
Even though a larger bike like this with disk brakes front and rear I do not feel in control sitting high up on a bicycle where my feet cannot touch the ground. However it is comfortable and I do not get cramps in my hip like when riding 20" bikes. The build will be a lightweight pedal assist belt drive approx 500 watts.
Since I am very low on cash at this time I may want to remove the 500 watt brush 24 volt motor and controller from the dual motor build and install a rear rack on the bike and mount the Unite motor on it for now. Later on when I get money I can replace with a brush less motor and use one of those brush-less controllers.
This way all I will need to do is order the part at the top of this post and a pulley to replace the motor sprocket and a belt. I will be able to afford it this month or next month and can power it with the Genuine Samsung LIFEPO4 battery pack for $36 and just use one of my 36 volt controllers. It can be geared for about 25 mph @ 36 volts and one horsepower (750 watts) as I will be able to pedal assist aggressively up hills with this bike as the gears work perfectly and I will be high enough so I will not have to bend my legs much. Please let me know if you guys are willing to help me with this. Thank you all.
PS. You will NOT see many more builds from now on with shitty brakes and no pedal chain or gears. I am sick of that and have aquired top quality bikes and parts for my future builds.
Also I just noticed a problem with the part at the top. It is for a 26" wheel NOT a 29" wheel. I could build the Haro V3 however. In fact the Haro V3 has disk brakes in the front. The rack is off the Currie and is extra heavy due to to support two SLA battery racks which slide down into it stock from the factory. I do not plan on running SLAS though. Probably a 54 volt LIFEPO4 pack. Also It is lower to the ground so I can plant both feet but still not too low and still comfortable. It is perfect for any of my Unite motors until I can afford the 1,800 watt brush less motor and a 54 volt custom built LIFEPO4 battery for 40 mph.
Also winter is on the way. I need a GOOD RELIABLE cargo bike. waterproof and winter ready. I have a 24" mongoose also and will now be taking the 800 watt 20" hub motor off the front of the Dimondback 20" BMX bike and installing it on the BACK of the 24" mongoose. I will be putting BMX style handlebars on the front for a front basket. - NO front motor.
It will have a large rear basket and a small front basket for even weight distribution. I need to order NOTHING. I have all the parts. Removing the rear hub motor should not be difficult like a front as no torque arms will be needed. Therefore I will be able to run the custom built studded tires DA invented if I want to. That will be an option.
The 24" cargo bike and the 20" dual motor bike will both be stripped down to the frames and the frames are going for scrap metal. Like I said I am sick of no pedal gears and brakes. I will be using the 48V 1,000 watt unite motor as well as the 36V 800 watt unite motor for a 40+ mph dual motor build with 20" wheels on a heavy duty 26" Huffy dual suspension frame. I will be ordering two freewheel clutches and two 8mm sprockets as well as two 10 tooth 8mm motor sprockets. The pedal crank will be removed and pegs will go on either the front or rear wheels. Doug will help me to install brakes for front and rear. It will be without pedal gears though but is ok as the cop will have to catch me.
PS again. The two bottom pics show how the motors will be both geared for 37 mph on the new 2 kilowatt dual motor build. Since the 36V 2,750 rpm motor will be running 3,666 rpms at 48 volts it will need the 72 tooth sprocket and the 48 volt 3,000 rpm motor will run the 54 tooth. both motor sprockets will be 11 tooth for 8 mm chain. It should reach 40 mph when I build a custom 54 volt LIFEPO4 pack.
I build e bikes. There not always pretty or practical but sometimes they work, at least for awhile. Immortality is not a dream but the future of our evolution. We were given the tools to forge our own destiny. We were created in gods image and shall evolve to live forever.
