I have an inexpensive Suntour 8 speed cassette with a 40t first gear. I may also change the rear wheel to a 26" which would lower the overall gearing 11%, almost another gear change lower.
There are 11 speed cassettes with a 50t low gear. That would be a fantastic setup for this drive. With a 26" rear wheel you'd have a very stout 14.2:1 low gear. Running 3000 watts or more that should get you right up the hill. The higher gears are not needed for running on the motor (they're beyond it's peak power range) but can be used for pedaling the bike if you want.
My motors don't have a planetary gear set so there is no noise from that. 219 chain is a thick, quiet chain compared to bicycle chain. My chain from motor to chainwheel is running 5x faster than the Cyclone 3000 and so makes more chain noise. My "small" motor is actually the same size and power output as the Cyclone motor. A full 1/3 of the Cyclone is gear box. My Big Block motor is twice the motor that the Cyclone is. It's the same overall width. I'll take photos and weigh them all very soon. I have a Cyclone 3000 sitting on top of the beer fridge in my shop to hold it down.
In addition to eliminating weight and complexity, the point of this new drive is to run straight reduction, making use of the large rear sprockets, rather than making a lot of drive reduction and then overdriving to the small sprockets on the rear wheel. The one and only reason to do that is to try to sync motor speed with pedaling speed. My first drives had a lot of reduction to allow users to pedal. As the power climbed from 1500 watts to 2000 to 3000 things started to break. Freewheels, sprockets and chains didn't last long. 10 gauge steel brackets bent. Just like the Cyclone 3000 it was too much reduction meeting too much resistance from an overdriven final stage. If you want to pedal with the motor keep the power down to 1500-2000 watts. If you want to run 3000 watts or more forget about pedaling. My plan with the single stage drive is to take it to 6000 watts and then to 15kw and beyond with new motors. Overdrive through bicycle chain and sprockets is not the way to do that.
Thanks for the heads up, haven't been here in a while, and no, I certainly don't resell anything (been here two years and counting now) and I only buy my kits directly from Paco in Taiwan when there is a need; however, as of lately I haven't really had much of a need to buy anything since nothing has catastrophically broken/failed in 7k miles... very happy with all my C3000W builds.LightningRods wrote:Be careful. People will think you're a shill for one of the Walmart-style Cyclone resellers.
If you do buy Cyclone kits, buy direct from Cyclone. http://www.cyclone-tw.com Support people who make things.
500 for the Small block or the BB?LightningRods wrote:The drive as shown is $595, $3OO less than my original two stage steel bracket drive. The stainless rear wheel sprocket is $5O and the stainless spacer set is $2O. Everything but the motor is made in the US and even that is modified here.
What about a trike with a regular BB? and chainrings?... say, I would like to use the Cyclone triple chainring and use your motor and mounting solution... which probably doesn't require any hacking like the C3000W did to avoid things breaking. I am contemplating building another more powerful trike for me (and give mine to my son) and obviously your 6000W kit seems to be something I could work with and crank the power down the road. The Cyclone 7500XL seems to be a bit too big for what I am looking and perhaps yours can fit the bill?LightningRods wrote:$595. The small block is 3" wide. The big block is 4" wide. This motor is 3.5" wide and splits the power difference between the two motors. It fits the width of the Beta frame perfectly. I'm selling this more powerful motor for the small block price until they are gone. The big block also fits the Beta well but is 1/2" wider than the battery box. It's $695.

If you want a bike for short, fun rides it doesn't make a lot of sense to carry 30 lbs of batteries. For as long as it runs the Beta should be more nimble and perform better than a heavier long range bike.
My answer to most of these decisions about which bike to get is that I want both!
Hi 80for20, yes, that's the right Allex... (2 l's!)80for20 wrote:Hey there PRW, I'm considering this frame but am not familiar with Alex's batteries. Is his thread the Adapto one?
