> USB Charging Ports - charge your electronic devices on-the-go.
You will only stand out if you have 1000Mah output because, guess what, Bosch already gives uss 500Mah. If you doo 1000Mah you win and people can port their GoPro/VIRB/whatever. If you do 500Mah you're not convincing anyone.
Bonus points: have hot-swappable USB/USB-C connectors. I know keyboards that do this. It's an advanced feature but will help you stand out.
>48V High-Capacity Battery - long range riding up to 100 miles on one charge.
Sorry, but unless you invented a super-efficient drive, 500Wh will only give 100 miles on a bare minimum of assist. If you want to compete, you have to come up with something better. 1000Wh is the state of the art (see Bosch DualBattery and such).
>Rear Rack - sturdy place to carry goods or attach child seats
Won't say no to that, so long as the mounting options are clear and available. Once you do anything proprietary, you've lost.
>Downhill Suspension Fork - get better handling, cornering capabilities, and a smoother ride.
Absolutely unnecessary. A 203mm suspension fork is only suitable for actual downhill travel, unless you've misunderstood what downhill is. The only thing you want to be using from the downhill discipline are rims and tubes. But this doesn't apply to fatbike components.
>SHIMANO M360 8-Speed Derailleur - smooth gear shifting for any terrain.
Derailleurs are evil and need to be replaced with IGHs on all ebikes. NuVinci isn't that expensive if you don't want to go for Rohloff.
>Front Light - visibility in darkness to keep safe.
Quality varies though. A cheap front light is not worth it. Lupine SL is where the it's at (affordable) or Supernova M99 Pro if you want to go top-tier.
Flashing Back Lights - visibility in darkness and turn signaling to keep safe.
Just keep them on but don't flash them. Too annoying.
4-inch Fat Tire - riding comfort while navigating on rough terrain.
This by itself guarantees absolutely nothing if you cannot drive the wheel properly.
Torque Transducer - allows the right amount of peddle assist.
It's called a torque sensor. Does not negate the need for speed and shift sensors.
Waterproof Cables - protects components of the electric bike from weather and wash.
Umm, they are waterproof by default on all ebikes. Imagine if they weren't!
Integrated App - provides real-time bike information and GPS positioning.
That's good if you can power the bike consistently. But the situation when the rider forgot their phone (or it's broken) needs to be accounted for.
Quick Charger - charge the electric bike in 2 hours, 50% faster than other electric bikes on the market.
This means your charger is 2x as big as chargers offered by what's on the market, right? Because you cannot cheat physics.
Travel Charger - portable charger to charge the electric bike anytime and anywhere.
I'd be OK with a charger that takes 8-10 hours to charge but is really small. Why? Charging at night while I sleep makes perfect sense.
