Hello! I would like to share the project I've just started for those that might be keen on following the progress and see how it will turn out.
Recently I've dusted off my old street bike with - similar to a - BMX geometry and 24" wheels, some new rubber and a brake refresh will cover most of the safety issues in it's current state. It's a chromoly frame from 2007 if I recall correctly. Build from scratch and went thru quite some punishment on the streets of The Hague and Rotterdam in the days.
Some of the specs of the bike that is going to be used:
NS Suburban frame
Atomlab handlebars
24" Atomlab rims with heavy duty DT spokes, 32 front, 36 rear, fitted with new Maxxis Holyrollers
Bolt on rear Chris King hub, with metal cassette body, quick release CK up front
Magura MT7 with 200/220mm disks
I've ordered a BBSHD, 52v battery and a box of extra cells, Phaserunner and CA to squeeze it to it's limits and likely a little beyond that
The goal is to create an esthetically pleasing bike, with a clean look. So no cables in sight, nice lines and not much going on in the handlebars area nor anywhere else. Used more as a scooter, but with very nimble handling, fast acceleration and more than decent brakes. Sub 50 pounds would be nice, but that might be a few pounds too much I'm asking for.
I've started to cut away some metal from the frame, so the motor can be mounted horizontally inline with the bracket and also get some more ground clearance. The downtube has also met the grinder, so a plate can be welded in that accepts the battery nicely on a flat surface. I'm a bit worried about the stress the bolts and rivnuts have to bare, when mounted on a round tube, so this solves that potential issue. Cutting away material gives also acces to the inside of the frame, where the wiring can be laid out, and I'll keep acces to it via some ports.
One of the last steps will be to connect the top front of the motor to the downtube, so it will become a structural part of the frame. The questionable bracket that clamps (!?!) the motor to the frame, will be welded as well.
Gearing will be a single speed setup, 30T up front and 12, 13 or 14T at the rear - with 24" wheels - for starters. Might have to change that, depending on the acceleration. 25-35 mph topspeed would be ok without pedaling.
I've attached some pictures of what's been going on till now, and I'm awaiting a Luna 30T sprocket, a singlespeed spacer set and the Phaserunner. As soon as I get some parts in, I'll update the thread.
Cheers!
