Balancing city and nature! The innovative performance of Sptebik's "20-inch electric fat bike"

Why is a 20-inch electric bicycle the ultimate companion for urban dwellers?

Two major benefits of the compact design

1. Stores neatly in the narrow spaces of bicycle parking lots in front of train stations

The compact body of 1550 x 1200 x 860 mm is 25% smaller in volume than conventional vehicles. The maneuverability provided by the 20-inch tires allows for stress-free travel even on crowded roads around Shinjuku Station in Tokyo.

2. Compliance with legal regulations

It comes standard with a 25km/h speed limiter that complies with the Road Traffic Act. A 2024 survey by the National Police Agency found that electric bicycles under 20 inches have the lowest traffic violation rate at 0.3%.

"Long-life design" proven by German ZIV survey

The lithium battery can be recharged 1,000 times , meaning it can be used for 10 years even if used 10km per day, reducing maintenance costs by 42% compared to conventional models.

Electric fat bikes make all-weather mobility possible

4.0-inch super-wide tires that can handle snowy and gravel roads

Grip power 2.7 times larger than the ground contact area

In winter tests in Asahikawa, Hokkaido, the slip rate was an astonishing 0.8% even on roads with 15cm of snow, ensuring stable riding even in areas where commuting by bicycle is difficult.

Shock absorption without suspension

The air pressure adjustable tube automatically detects unevenness in the road surface. In farm road tests in the Tohoku region, it succeeded in reducing vibration transmission rate by 67% compared to the previous model .

Outdoor-friendly expandability

180kg load-bearing frame

The carrier, made of reinforced chromium-molybdenum steel pipes, can carry 100kg of camping gear plus one adult (80kg total). In durability tests conducted by the Ministry of Land, Infrastructure, Transport and Tourism, it has been proven to be 1.8 times stronger than the JIS standard.

Waterproof performance IPX6 certified

The motor controller is completely protected even in sudden heavy rain. In a rainy season demonstration experiment in Miyazaki Prefecture, Kyushu, zero malfunctions were achieved even after 72 continuous hours of rain.

The true value of the 48V500W motor

The torque characteristics allow it to maintain a speed of 25km/h even on a steep 20-degree gradient. In a test run at Shibu Pass in Nagano Prefecture, the average climbing speed was 28% higher than that of competitors .

The synergistic effect of the 7-speed Himano transmission

From the light "ECO mode" to the powerful "Hill Climb mode," the system automatically suggests the optimal gear ratio according to the road conditions. A user survey showed that even on the hilly streets of Osaka City, heart rates were reduced by an average of 15%.

Voices of outdoor enthusiasts living in Yamanashi Prefecture

"It can comfortably ride even on unpaved roads at the foot of Mt. Fuji. The grip of the tires and the cushioning of the saddle are excellent, so now I can enjoy exploring forest roads that I had previously given up on."
