Dynalion K7-2: 768 Watt-Hours, and the Frame Is Steel and Aluminum
Dynalion’s K7-2 page, read 17 October 2026, is the fat-tire bike at $1,999. The pack is 48 volts and 16 amp-hours. Forty-eight times 16 is 768 watt-hours. The cart does not print that. A tile says 1,000 watts. The same page says a 1,500-watt peak. The controller is 48 volts at 30 amps, which is 1,440 watts. The frame tile says steel. The parameter line says A6061 aluminum. Range is 30 to 50 km, and also up to 60 km. Forty-five km/h and 28 mph are the same speed. There is a twist throttle. That is not a Class 2 and it is not a Class 3.

The short answer
The Dynalion K7-2 is $1,999. The pack is 48 volts and 16 amp-hours. Forty-eight times 16 is 768 watt-hours. The page prints a 1,000-watt motor, a 1,500-watt peak, and a controller at 48 volts and 30 amps, which is 1,440 watts. The frame is called steel and A6061 aluminum. Top speed is 45 km/h, which is 28 mph, with a twist throttle.
The Dynalion fat-tire bike on the company’s own site is the K7-2, and the page does not agree with itself. Dynalion.com, read 17 October 2026, prices it at $1,999. The sale price and the regular price are the same number. The pack is 48 volts and 16 amp-hours, swappable. Forty-eight times 16 is 768 watt-hours. The cart never prints 768. A tile says 1,000 watts, 30 to 50 km, 45 km/h, 45 kg, and a steel frame. The parameter block says a 48-volt 1,000-watt rear hub, and the page also prints a peak of 1,500 watts. The controller, on that same block, is 48 volts at 30 amps. Forty-eight times 30 is 1,440 watts. One thousand, one thousand four hundred forty, and one thousand five hundred are three power numbers. None of them is labeled nominal.
Dynalion K7-2 cart, 17 October 2026. eStar Rides is a sold-out reseller page, not a second official spec.
| What it prints | |
|---|---|
| Price | $1,999 on Dynalion. eStar also says $1,999, sold out, and the brand field on that page says Dynavolt. |
| Pack | 48V 16Ah. 48 × 16 = 768Wh, unprinted. Charger 54.6V at 2A. No charge time on the cart. |
| Motor | Tile: 1,000W. Parameter: 48V 1,000W rear hub. Page also: 1,500W peak. Controller: 48V 30A = 1,440W. |
| Speed | Tile: 45 km/h. Parameter and the collection card: 28 mph. 45 ÷ 1.609 = 28.0. Those two agree. Twist throttle. |
| Range | Tile: 30–50 km. Parameter: up to 60 km. 60 is not inside 30–50. |
| Frame | Tile and the scrambler copy: reinforced steel. Parameter: A6061 aluminum. Both are on the product page. |
| The rest | 20 × 4.0 in tires. Shimano 7-speed. Hydraulic discs. Front suspension fork. A “heavy-duty rear suspension” line, no millimeters. Weight 45 kg. Max load 120 kg. The sensor line reads “speed Torque sensor.” No newton-meters. |
Forty-five kilometers an hour is 28 miles an hour
The tile says 45 km/h. The parameter says 28 mph. The collection card also says 28 mph. Forty-five divided by 1.609 is 28.0. The pair agrees. What does not agree is the throttle next to it. The parameter lists a twist throttle on demand. The class chart stops a Class 2 throttle at 20 mph and gives a Class 3 pedal assist to 28 with no throttle doing the 28. A twist throttle and a 28 mph ceiling, printed together, are not either class. GoldGuy’s 2024 title says 32 mph, and in the ride he calls out 35 and 40 on the screen, then says the display is reading too high. A display he does not trust is not a new top speed for the 2026 cart. His description also says 1,200 watts. One thousand two hundred is not 1,000, and it is not 1,500. It is a third year’s motor line. Do not paste it onto the bike that is $1,999 today.
Seven hundred sixty-eight watt-hours, and 60 is outside 30 to 50
Thirty kilometers is 18.6 miles. Fifty is 31.1. Sixty is 37.3. The tile’s band and the parameter’s “up to 60 km” are not the same claim. Sixty minus 50 is 10 km, about 6 miles, and the page does not say which one is assist and which one is the throttle. Seven hundred sixty-eight divided by 60 is 12.8 watt-hours per kilometer, if the longer claim and the pack are a pair. That is 20.6 watt-hours a mile. The range page is why a band with no rider weight is not a loop. The watt-hour page is the 48 times 16. The charger is 54.6 volts at 2 amps. Fifty-four point six times 2 is 109.2 watts. Seven hundred sixty-eight divided by 109.2 is 7.0 hours, if that watt held the whole time, which a lithium charge does not. The cart prints no charge time. A 4-hour charge of 768 watt-hours would average 192 watts. One hundred ninety-two divided by 54.6 is 3.5 amps. The printed charger is 2 amps. A page that promises a 4-hour charge is not describing this charger.

Steel in the headline, aluminum in the table
The opening copy says a reinforced steel frame, classic scrambler, city cruising. The spec tile says steel. The parameter says an A6061 aluminum frame, and the fork is also A6061 aluminum, with suspension and no travel. A later line says heavy-duty rear suspension, also with no millimeters. Front and rear, or a fork only, is not settled by the adjectives. The tires are 20 by 4.0 inches. Four times 25.4 is 101.6 millimeters. The tire page is the width. Gears are a Shimano 7-speed. Brakes are hydraulic discs, front and rear. The bike weighs 45 kg. Forty-five times 2.2 is 99 pounds. Max load is 120 kg, which is 264 pounds. The page does not say whether 120 includes the 45. The sensor line is the words “speed Torque sensor.” There is no newton-meter next to them. A mashed label is not a torque figure. The motor page is why 1,000 watts, a 1,500-watt peak, and a 1,440-watt controller are three sentences.
Forty-five kilometers an hour is 28 miles an hour. Steel and aluminum are not the same frame.
eStar Rides lists a Dynalion K7-2 at the same $1,999 and says it is sold out. Its spec table offers 500, 750, or 1,000 watts, about 28 miles on the motor and 40-plus on assist, a top speed up to 32 mph, brakes that are mechanical or hydraulic, a frame that is steel or aluminum, a 4-to-6-hour charge, and a 200 kg load. An extra table on that same page says 500 watts, a 48-volt 15-amp-hour pack, mechanical brakes, 60 miles, and 440 pounds. Forty-eight times 15 is 720 watt-hours, not 768. Two hundred kilograms times 2.2 is 440 pounds, so that load pair agrees with itself and disagrees with Dynalion’s 120 kg. The brand field says Dynavolt. None of those rows replace the cart. A short January 2025 clip with Dynalion in the title has no specs in the words. The GoldGuy film is the one with a date and a motor number, and that motor number is from 2024. Buy the $1,999 page for the 768 watt-hours and the throttle. Do not buy it for a class, a single frame metal, or a single range.

What Is a Class 1, 2, and 3 E-Bike?
Class 1 is pedal-assist to 20. Class 2 adds a throttle to 20. Class 3 is pedal-assist to 28. A Tuttio is none of these. The sticker is not the trail.

Understanding Volts, Amps, and Watt-Hours
Voltage is pressure. Amps are flow. Watt-hours are the tank. The hangtag that only says 750W is selling you one of those three.

E-Bike Tires: The Size on the Sidewall, Not the Pretty Name
A 29er and a 700c share a 622-millimeter bead and are not the same tire. Four inches is about 102 millimeters. Pressure is the range printed on that casing. Schwalbe’s E-50 mark is a European approval for machines up to 50 km/h, not a US class sticker.
