The Juicer 48 is custom-built motorized bicycle that reaches back 100 years for its form, while leaning forward for its function. Calling on his background in design, its creator Dave Twomey combined his love for electric propulsion and vintage machinery to create a retro ride whose main focal point is a pair of battery banks that recall the look of a V-twin engine.

Twomey started the project by recycling a bicycle frame and having the down tube stretched into a loop to accommodate the Manta DC motor and his Headway lithium iron phosphate (LiFePo4) battery packs. He then attached a self-fabricated set of springer forks up front and gave it a nice set of Felt "Thick Brick" hoops to help set off the cruiser look.

While most of the propulsive bits are left exposed, the tank up top houses a 400-amp controller as well as a BMS (battery management system). As shown in the gallery photos, the front is now adorned with a 113dB horn to scare the hell out of alert texting drivers or anyone that might step out in its path. Twomey thought this a prudent precaution since it's pretty quick and can hit speeds of 46 miles per hour. At a more reasonable 20 mph, the 16 LiFePo4 cells hold enough energy to carry the 110-lb bike and rider about 13 miles.

The Juicer 48 may still get a few finishing touches, but early feedback favorable to its current state may keep it from receiving its planned paint job. If you happen to be in the Los Angeles area, you can check it out in person at Hollywood Electrics where it will be hanging out with Dave's earlier and equally awesome creation, the Juicer 36, over the Christmas holidays. Hit the jump for footage of some sweet sweet 48-volt motorized bicycle action.

      Love the look I am a little concerned that the seat position will skew the weight balance too far back to be balanced, and am also concerned about the safety of exposed chain drive, but the look is fab!

      • Gumption is a human trait, not something mechanical. This seems more like an anti-gumption device. And this is green ... how?

      There's a motorized bike forum here if anyone wants to know how to build one http://www.motoredbikes.com

      This machine was the horrible. It would leak and actually spray the pulp across the room. It would yield a very small amount of juice and is useless if your trying to juice greens. The pulp would be wet which meant your house would smell and attract fruit flies unless you emptied the garbage right away. Invest in a macerating juicer. A little more money but it will pay for itself in the long run.http://www.juice-reciping.com/kuvings-nj-9310u-centrifugal-juicer-orangekuvings-centrifugal-juicer-b001v7p68m.html

      funny although I like hubmotors better for bicycles for the elegance. and they can be quite powerful.

      nice use of the cylindrical cells in the design.

      Saw this ebike on my forums last year. It's a very nice show piece :) The headway cells are stunning in that configuration but the sad reality is that those cells are awful! But the creativity here wins :) This is one of many awesome showy electric bicycles i know of. ABG, if you want to feature more, hit me up.. i'm 'neptronix' on the endless-sphere forum.

        Curious on Dan's question, but then if true, can they be replaced with something that works and still looks cool?

          They are lithium phosphate chemistry, very heavy and low energy density. Good for a hybrid car but not an Ebike. A better cell would be lithium cobalt, they are much lighter and the bike would run 30-50% longer on a charge

          Nicholas, they are not very heavy. lifepo is 90-130Wh/kg. plenty for an electric bicycle. and they are much more robust and long lived. I would not use cobalt cells

        how are the cells awful?

        headway cells seem to be quite good. 2WM is quite wrong. some even use them for electric cars and they are fairly powerful. from what I know it's a good cell and easy to work with

      O sweet! Classic! I love the billetproof, steam punk ness of it but seems as if the driver is a tad big for the bike.. Don't improve it too much now.... it's perfect.

      The right tool for the job in LA. Great style!
