GUN JUMPER

[sdframe]

When I read that the upcoming RRBBO 19 would allow e-bikes, I got quite excited. I had been ruminating about building a rat e-bike for some time now. I started gathering and ordering parts and dug out my favorite pedal-powered rat for some revamping. Not that it needed revamping; it was a joy to ride with a wonderful 7-speed internal hub coaster brake Shimano wheelset, tan balloon tires and a cushy ordinary saddle.

As I gathered the parts from here and there, I couldn't help but start to replace them, and before I knew it, I had a finished rat e-bike. It's fast, with a 1500W motor, and it rides nicely. I am waiting for a disc brake ready, Monark-style springer fork to come from China, and it'll be done.

I totally jumped the gun on RRBBO 19, but I do have a new ride to play with. I'll just have to sit back and watch you guys come up with some wonderful creations.

Now that is cool. I have a similar build in mind for the future. I like how your battery and electronics follow the V pattern and the eclectic mix of parts. Really cool!!

Can't go wrong with a Rollfast!

Regen for rear wheel braking ?

Regen for rear wheel braking ?

No. just a very basic motor kit.

I hadn't noticed the V pattern. I always admired V-twins.

I wasn't thrilled with the zip ties holding the cables to the frame, so I dug out some old metal clips for a vintage look. I also ordered two decals to show that my rat is electrified.

I'm still waiting for shipment of a disc brake ready springer fork.

looks like fun!

My Monark-style springer was delivered, but the steering tube was too short! I'll just save it for the future.

So that left me with a front wheel with a useless brake disc attached. I got rid of it.

I think it looks cleaner, but now I'm wondering why not just find a spoked front wheel that more or less matches the rear? Back to the storage unit. I may have the right wheel there.

I corrected a few more design issues, changing out the front wheel to more or less match the rear, replacing a flimsy front caliper with a more beefy one, and adding truss rods off a modern Electra, just for looks. Maybe I'm finished for now.

On my GPS phone app, I clocked it at 31 mph full throttle down my street, and 30 mph back up.
