Range test?

I understand that the range is said to be close to 50 miles, but that does vary depending on what mode/speed you ride at.
I know that a range test in all different modes would take some time to test but with that information I will feel much better about buying if I know a real range for all modes
(Talaria boys have a good method of testing e bikes)

More volts = More better!

The Altis Sigma really seems like a beast of an off-road e-bike. The 98V battery paired with its massive 3400Wh capacity gives it serious range and power. The quality of parts, like the moto brakes and adjustable air suspension, stands out, and the option to pick your rear wheel size is a nice touch. With 20kW of peak power, it easily beats out competitors like the Ultra Bee and MX5, all while staying relatively lightweight. Plus, it has a clear TFT display, fast charging, and a low-maintenance gearbox. Honestly, the only thing I’d love to see is a ready-made 16” supermoto wheelset for some road action.

What really grabs my attention is the attention to detail and versatility. You can tune the suspension to match your weight, which is great for ensuring you get a smooth ride, whether you're cruising or hitting rough trails. The bike also comes with a full light set and working brake lights, so you don’t have to worry about visibility if you ride at night.

On the tech side, the large TFT display offers tons of info and lets you easily tweak the power settings, which is a great feature to have while riding. The fast charging is a huge plus, hitting the max wattage that most American outlets can handle, so you can charge it quickly between rides.

The gearbox is a big win for me too. With a five-year oil change interval, it’s super low maintenance, and you won’t have to deal with issues like snapped belts. It’s ready to go for the long haul. Also, the fact that you can use the bike in e-bike mode with a 20 mph speed limit makes it versatile enough for more regulated areas.

Overall, it seems like the Sigma offers a ton of performance and features in a well-built package. It’s just missing that road-ready 16-inch supermoto wheelset to be the full package for both off-road and street riding.
