    Well, Corona virus may be in all the headlines right now, but I've eventually succumbed to another kind of bug, eBikes, God forbid!
    Scored a great deal on a one-off, show winning, stretch cruiser on eBay here in the UK that I just knew I'd regret if I didn't snap it up. After my 'best offer' was accepted, it was couriered to me a couple of weeks ago and I couldn't have been happier with my purchase.

    Thanks to folks on RRB forum, forks and rear triangle were identified as being from an OCC Stingray, with a very well done custom stretch frame. Spent two weeks 'creatively staring' at the bike parked-up in the living room whilst formulating my build plan....
    Decided it would be 48v 1000w rear eHub powered - a first for me following my three earlier gas powered projects featured on this forum.
    Work commenced this last week, starting with swapping-out the original 24" 40 spoke, rim braked Stingray front wheel for a new 36 spoke rim laced to a Sturmey Archer 90mm drum brake. Brake's lever arm needed shortening, drilling and a turned bushing made to mate it to a clamp big enough to fit round the larger Stingray fork leg. Never been a fan of triple tree type forks, so something more to taste was inevitable fork wise. Came up with the idea to create something more springer vibey using the original forks mated to a set of cnc'd alloy riser parts, 2 lengths of 22.2mm dia. stainless tube and a pair of rubber fork gaiters. The pics show where I'm at after test fitting these parts. Still need to come up with a plan for how the lower ends of the s/s tubes will fit to the axle nuts - probably via rod ends I reckon.
    New wider cruiser bars to be fitted. These will install to the steerer tube using a new stem riser and a 32mm ahead (or in this case astern) clamp for a very comfortable and relaxed ride - at least for me anyhow.
    Going with the name BLUE BAMBOO for this project. Frame is undergoing the 'bamboo' transformation process using rings of half round brass stock rolled to shape in my rolling bars. After annealing, the brass rings fit snug to the frame and are permanently secured using polyurethane adhesive. The rings will be blended-in using some body putty to create a more organic bamboo profile. I'm in the process of creating the different sized brass rings to fit the three different sized tubes used on this bike's custom frame. Laborious - but the results will hopefully be worth it. Once the 'bambooing' of the frame is completed, I'll repaint it to represent exotic blue bamboo. Google it.
    Still haven't unearthed my tyre irons from the storage facility since our house move last year, so I'm off to the local tyre fitter's tomorrow to have the new tyre/tube installed on the 20x4 eHub rear wheel.

    Awesome. Are the brass rings your idea or is it something you have seen on older bikes or motorcycles? I've seen them on vintage rifles.

    Using half round brass stock rolled into rings was simply the best way I could think of to represent bamboo's segmented look. Once blended in the whole frame will be repainted - so the brass rings will be over-painted then airbrushed to create the shadowed/mottled look of real blue bamboo.

    Front forks completed. Used 16mm rod ends to secure the lower ends of the leading fork tubes to the axle. I drilled/tapped the axle nuts and used m5 bolts passed through a plastic dust cap to fix things firmly.

    Wide, pull-back cruiser handlebars provide an old guy like me with a much more comfortable, relaxed riding position.
    DSCN3663.JPG New eHub rear wheel temporarily installed. Gonna either cover the hub motor with chrome vinyl wrap or repaint it silver. Front wheel will get a new black rim and spokes, then I'll apply blue coloured Rimblades to the edges of both front and rear wheel rims to co-ordinate with the repainted blue frame.
