I just viewed the Trail version. Looks very sweet. My only concern was the 250w motor. Is that enough for a trail bike. Great gearset, 40T on rear cog

I rode the Trail version around SF and it's pretty peppy. It didn't feel underpowered at all. I think they're understating the motor power. It probably won't take you up to 30MPH on flat ground, but it accelerates quite quickly to 20MPH. I didn't try it up a hill but I imagine it'd climb well, considering that it's a mid-drive and can use the mechanical advantage of the rear derailleur's gearing.

I looked at it a week ago. Looks great on paper but they have not disclosed the price.
I don't think the Roadster model is any more competitive than Juiced Cross Current. Same frame/battery placement.

I like that they chose the SR Epixon front suspension fork for their Trail and Attack models. Same fork that Stromer chose for the ST2. Quality air fork and brakes all on a bargain-priced bike.

UPDATE: Flux has since downgraded the front suspension fork on the Trail model to an SR Suntour XCR coil suspension fork. They're calling it an 'oil suspension' instead of a coil suspension, but I believe it's a typo. I asked if it's the coil model or the air model, and they replied and said it was an 'oil' model, and since they didn't say air, I naturally assume they meant 'coil'.

I couldn't find anything on the Bofeili mid-drive. The text of the IGG page suggests it would be possible to get more watts out of it. Someone could ask where the controller maxes out. I don't know if I want a mystery mid-drive with no obvious source for parts or service. They are getting some money. Eventually bikes like the Monte Capro, the Cross Current, and the Attack have to chip away at the stuff from Europe.

Bofeili motors power some Optibike models, and they've been making mid-drives since at least 2014, if not earlier, and most of their motors advertise 450W, so this motor could actually just be a 450W unit that's badged as 250W for regulatory compliance purposes (they want to sell in Europe/Australia, which have lower power limits for ebikes). One of the big benefits of the Bofeili drive is that it integrates right into the bottom bracket, so you don't have some big bulbous motor that mounts in front of the bottom bracket like the Bafang BBS01/02/HD motors. I imagine it could be harder to find parts for the Bofeili drive vs. Bafang motors, but not impossible.

Does anyone know anything about the pedal assist system on the Flux bikes? Cadence only or does it include a torque sensor (can't seem to find any discussion of that point online).

There's little information on the drive system they are using. It's a very nice looking bike with a lot of potential but the drive system i know nothing about it. It looks like 250W seems under power for the North American market.. I may be wrong, But I know personally I enjoy ebikes over 500W from the number of test ride I've been on.

Pricing on the Flux bikes is listed on their Indiegogo pages; retail after launch will be $1999 to $2699, so not less expensive than the Cross Current. Also the motor is the same as what is used on the Canadian eProdigy bikes, but the lower wattage European version according to electricbike.com.

Here is a break-down diagram of the drive system of the Bofeili motor.

-from their web-site.

Thx Ann M. & BikerJohn, I think I understand this drive system. So I guess this motor can do 500W with some playing around with control settings then. The stealth look of this drive unit is what impress me the most and the Flux is high on my list at the moment.

High on my list too. The next e-bike for me will definitely be a crank motor, under 50 pounds total weight with at least 12-20Ah battery capacity and a price tag <$2500.

Nice bike. Zero reason for it to be crowd sourced.
There are plenty of reasons. When it's crowdfunded, there is no dealer to mark up the bike, so you can sell the bike for 30-40% less than retail. These bikes would surely be selling for $1,799 - $2,299 at a dealer, whereas on Indiegogo, they can sell them for $1,099 - $1,699.

The only problem is that there is nobody to go to for local service, and you have to put the bike together or pay a shop to do it.

Wondering if this bike will mash gears under load when shifting. Price at igg is very tempting. Would this bike be worth it even if does wear gears down more quickly?

Fact is most arent' selling them for 30-40% less than "retail" (what is that?) and the sucker/customer is simply FRONTING THE MONEY to a business starting up, with NO GUARANTEE of a product being delivered at the advertised price (seldom to never) to not being delivered. Ever. (not uncommon)
Then there's the lack of service, or even a dealer to help when you do break down! Good luck trying to find someone to work on a no name Chinese clone e bike.
Simply nutzo.
Sonders caught a wave of uninformed Ebike wanna be's with an artificially low price and the only way he survived it is because SO many people gave him money on spec that he could afford to eat the losses on a $600 E bike. (single speed!) IF he hadn't gotten all that money up front and had simply opened a shop selling those bikes at that price, he would be long gone now. (not only my opinion)
Did you buy one? ;)
