I'm with u guys on this one, what the ebike industry needs is
a) some standardisation, with charts, data and information released as soon as the product is.
b) have properly designed products
c) start focusing on quality products designed for bikes of a specific nature or sizes of bikes.

with regards to b and c - that is where the biggest issue is in my opinion. There is too many non standard parts - and by that i mean parts not designed to fit correctly into a bike with 135mm dropouts. I would also like to see a "downhill" version of hte x5 designed to fit into downhill bike dropouts - which are different, one side is screwed in the other is clamped in. this and the addition of motors to fit would greatly help the adoption of the ebike DIY market. Also using latest common components (ie a shimano 8 speed or 9 speed hub (i konw itst a tight fit) on the motor, and making the motor narrower but larger in diameter would help too.

I hate to say it but i think we might need to get some other countries designing the motors and stuff, but having the existing manufacturers making them - to bring the benefit of correct design and low cost.

I have to say i'm impressed with crystalite's LATEST controllers (especially the ones Justin had them make with 4110 fets), their 35a controllers come with 3140 fets which are also very good (i'm running one of these) the motors still have a ways to go, but the developments of the puma based motors is going along at a nice rate, esp with the latest styles that their doing - with metal internal gears (its a hub motor)
