We also caught the debut of brd Motorcycles 2013 Redshift MX bike. The company’s industrial designer, Jeff Sand, said the electric motocrosser has the power output of a Lites class motorcycle. A peek at the spec sheet reveals it has a claimed 65 mile range with a top speed of 65 mph. It is powered by a 40 hp PMAC, liquid-cooled brushless motor with a 5.2 kWh Lithium-Ion battery. The front is anchored by a WP 48mm inverted fork with 11.8 inches of travel to go with a WP monoshock on the rear that is adjustable for preload, rebound and compression. It tips the scales at a reported 250 pounds and by all appearance is a solidly built ride, but its $15,000 sticker price is sure to raise a few eyebrows
jonescg said:Not necessarily. I was getting 70 Wh/km from Voltron around the streets... not sure how many bushels to the cubit that is, but seems pretty good to me.

A motorcycle consuming half of what a car consumes doesn't seem too low to me.
bearing said:I wrote that wrong. Leaf consumes 160Wh per mile at that speed (not per km). I initially wrote 100Wh/km @ 56km/h, then I converted it to american units, and missed to change the actual unit.
Thud said:on topic
I sat on one of these at the motorcycle show in Indianapolis last saturday.....it is a pretty nice bike. full White power suspension packadge (means totaly tunable for a guy like me). the guys were all talking to other dealer reps when i was in their booth but i could hear the tall tails about ho GReat this unit is going to be!
anyway the show model was all production parts & it was totaly detailed.....every thing was in its place & no loose ends anywhere. I really wanted to try one out...but that was not a posibility.
I am talkiing to my local dealer about picking up Zero's or these...or something....He's disgruntled with Honda after getting his teritory steped on by a growing super dealer in the area (who is dealing all 4 jap brands now after buying up all the other bike shops in muskegon)
any way...i was impressed....waiting for the E-motocross soot out in MXA soon
When you look at the total cost its comparable to a normal 2 or 4 stroke mx bikeThud said:They just need to carve 30 pounds off the weight.....& 5k$ off the price.
in theory, the e-bike should be a more cost effective bike to build....far less total parts & the parts that are there are already mature technology.
I still think the marketing departments are tying to capitalize on the perceived "green revolution" & maximizing profits by marketing to the upper end niche market.
If some one really tried & didn't care about getting "rich quick".....it could done far more mass consumer friendly money wise.
They do offer J1772..... Both Zero and Alta.... Its an option.flathill said:Finally a real motorcycle with a liquid cooled motor and controller so you can actually race it in the desert without overtemp mode kicking in
I love the bike but it needs a J1772 port. I don't understand why Zero or Alta don't offer J1772 like Brammo. All they have to do is design their own controller with an integrated charger like Mission has done to keep the weight down (or just use the Mission controller). The big thermal mass of the liquid cooled controller is useless when the bike is being charged. Just slapping on a charger to the same aluminum slug will save a ton of weight. This way the slug is being used at all times (but never at the same time). We don't need DC fast chargers for motorbikes. J1772 allows up to 16.8kw which is plenty fast. That would charge the current bike 5.2kw pack in 20-30 min. J1772 NOW PLEASE AND I WILL BUY!
Please show off the guts of the new 18650 pack. Thanks guys
