High performance requires high amps, but LiPo batteries can be dangerous for someone who is inexperienced with them. LiPo is capable of putting out VERY high current (the C-rate), and if you are building a racing E-bike, they are simply the best
Mid drives are taking the electric bike world by storm this year, and they were the break-out story of 2013 at the two biggest international bike shows. The big global bicycle manufacturers have added dozens of mid-drive models to their
50mph Electric Trike
Matt Shumaker builds a 50mph electric trike using a giant Astro Flight 3220 RC Motor and lipo battery packs from hobby king [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_kmxxtrike.jpg] 406 0 3/20/2010
Here is my latest build. It started life as a KMX Typhoon. Here you can see the stock trike. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_stripped.jpg] 339 0
First I stripped the frame. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_beadblasted.jpg] 313 0
Next the frame was bead blasted. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_widened.jpg] 307 0
I decided to widen, lengthen and lower the frame. I settled on 5 inches wider, 3 inches longer, and 3/4 inch lower.In this picture, you can see the frame cut apart with inserts fabricated. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_welded.jpg] 281 0
and then the frame welded together [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_reinforced.jpg] 320 0
Next I took the stock seat frame and welded it to the mainframe in a Space-Frame arrangement for added strength (after being stretched and lowered) and for added torsional rigidity. I like the trellis look. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_powdercoated.jpg] 324 0
For quite some time I have wanted a yellow and black bike or trike. To that end, I had the frame powder-coated Safety yellow, then clear coated. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_widerims.jpg] 348 0
For a high powered trike, the stock one inch wide rims weren’t enough. So, I had custom rims made for me oversees. These are 1.75 inch wide (front) and 2 inch wide (rear) rims. They were also powder-coated yellow and clear coated. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_frontwheels.jpg] 354 0
You can also see the front rotors. These are 203mm units (up from the stock 160mm). I also installed Hope 4 piston calipers. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_driveunit.jpg] 548 0
The drive unit for this trike consists of two Astro Flight 3220 motors that were custom made for this application. They use larger than stock (1/2 inch as opposed to the stock 3/8 inch) shafts with outboard bearing supports. They are wound for 14,000rpm at 48 volts. These motors were dyno tested for me at 14hp each.
That is 28hp total! The torque is nearly 100ft pounds at the rear wheel. I expect 0 to 60 in 3.5 seconds (it has the power to weight ratio of a shifter kart). The reduction unit I machined in my shop. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_torquearm.jpg] 412 0
I machined a torque arm and chain tensioner to help keep things in line. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_drivealigned.jpg] 433 0
Here the drive unit and torque arm assemblies are installed. This part was time consuming but very rewarding! There is such tight confines in this frame.
However, I finally got all equipment mounted and lined up. Now, I need to take it all apart for final anodizing of the remaining bar aluminum parts! [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_drive2.jpg] 468 0
Here is the right side of the installed drive system. The bare aluminum cover will be anodized black, then engraved in the CNC. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_drive3.jpg] 427 0

Here is one more shot from the right side showing the chain routing over the tensioner. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_steeringdampener.jpg] 389 0
Here is a shot of the steering dampener. This is a basic aftermarket allow, adjustable dampener. I learned a while back that high speed on a trike requires dampening! [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_twobrakes.jpg] 382 0
I decided to run two separate master-cylinders (one for each front brake) that are activated individually by two fingers on one hand. The left front brake is operated by my left middle finger while the right front brake is operated by my left index finger. This gives differential braking for cornering and smokey donuts! [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_throttle.jpg] 357 0
The throttle is a Magura twist grip modified to be a thumb throttle. It looks really nice next to the stock KMX grip shifter. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_drivemounted.jpg] 381 0
One more shot of the drive unit from above, rear. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_y5.jpg] 375 0
You can see the custom tillers. These are upgraded tillers we CNC machine for the Catrike line. However, I decided to run them on this trike. They are nice because of the adjustability.
Plus, they work much better in the Motorcycle layout rather than the stock vertical tiller arrangement. In the initial portion of the build I neglected to give many details of the creation of this trike. But, I must say, these tillers to not just bolt onto a KMX trike. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_batterybox.jpg] 473 0
I run Lithium Polymer batteries on my bikes. For this build I decided to make some CNC machined battery boxes. So, to that end, we machined a bunch of twin pack boxes. Here is the first box. They will all be anodized black eventually. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_batterymount1.jpg] 377 0
Here you can see a machined aluminum battery box mount plate. This was made to give a hard-point for the heavy battery boxes to mount to. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_batterybox2.jpg] 393 0
Here are the finished black anodized battery boxes mounted to the frame. The covers will also be black with CNC engraving on the top. [img src=http://www.electricbike.com/wp-content/flagallery/50mph-electric-trike/thumbs/thumbs_seatdone.jpg] 350 0
The trike has been turning out so well, I decided the stock seat cover just did not look very good. So, I went to an embroidery shop and had some cool stripes embroidered in yellow to match the frame. This small detail really ties the seat cover into the look of the rest of the trike

Astro Flight 3210 RC brushless motor. RC motors put out a lot of power for their weight but spin way too fast so need some kind of gear reduction before they can be used on an ebike.

On top of the motor a planetary gear reduction system is installed giving the motor a 12:1 reduction. the motor can now use the same drive train (and gears) as the pedaling rider does.

The bomber has the popular cycle analyst batter monitoring system built into the frame. a very nice touch. [img src=http://www.electricbike.com/wp-content/flagallery/stealth-bomber/thumbs/thumbs_bomber_trio.jpg] 447 0 Trio of Bombers

The Bomber weighs in at a hefty 120 pounds. it takes a lot of practice before you can get goofy on it safely. Also remember the stealth because of the rear motor weight, is not well balanced.

This gearbox system was decidedly too complicated and heavy for the pedal bicycle crowd. but Stealth obviously saw it as a perfect ebike solution and designed their frame around it. Remember the Bomber doesn’t even have a built in motor, but it does have a built in pedal gear box!

The Stealth factory in Australia is cranking out electric bicycles. Apparently the demand is so great for the stealth bomber, that at times there is a waiting list.
