Spiny 2: $349 on Kickstarter. The 56 Miles Is 4.75 Watt-Hours a Mile.

The Spiny 2 is not a bike you can buy from a shop today. Electrek, Micah Toll, 16 October 2026, says it is a Kickstarter friction drive that snaps onto a bicycle, and he writes that he has not tested it. Deliveries are estimated for April 2027. He says that date is not a guarantee. The company says it has already shipped hundreds of the earlier unit. That is a record of a previous product, not a ride on this one. The pledge page this desk opened asks $349 for one Spiny 2 and calls that $211 off, 38 percent. Three hundred forty-nine plus 211 is $560. Two hundred eleven divided by 560 is 0.377, which they round to 38 percent. The extended-range bundle is $479, called $320 off, 40 percent. Four hundred seventy-nine plus 320 is $799. Three hundred twenty divided by 799 is 0.40. Electrek does not print a price.

Four point seven five is the brochure

Two hundred sixty-six watt-hours divided by 56 miles is 4.75 watt-hours a mile. That is the claim, under ideal conditions, with no rider weight next to it. Toll’s sentence is that unless you are doing the pedaling of a pro, the 266 will not get a normal rider anywhere close to 56 miles on an average day. He did not publish his own loop, because he did not ride it. A second pack, on the pledge, is said to double the claim to 180 kilometers and 112 miles. Ninety times two is 180. Fifty-six times two is 112. The doubling is arithmetic. The page does not say the second pack is another 266 watt-hours. If it is, the pair is 532, and 532 divided by 112 is the same 4.75. The watt-hour page is why a small pack cannot be talked into a long claim. The September sheet’s 25 volts, which Electrek does not repeat, would make the 266 a 10.64-amp-hour pack. Two hundred sixty-six divided by 25 is 10.64. Leave that on the September page until the pledge prints a voltage.

Three seconds is the second step

Electrek says the mounting hardware and the sensors go on the bike first. After that, the drive clicks on and off. The headline’s three seconds is that click. The pledge says “around 3 seconds,” which is not the headline’s “just three.” The first mount is not in either number. It is a friction drive: a roller on the tire, not a hub and not a mid-drive. Toll calls that less elegant and fast to fit. The fit list is not every bicycle. Rear-suspension bikes are out. A normal rear fender does not stay. Rim brakes and disc brakes are both claimed. Tighter frames and a Brompton need an adapter. The 1 October page already filed Jeremy Benson’s 30 September list of those exceptions. Benson did not test it either. No public YouTube id for the unit turned up. The pledge page has a player. This desk will not treat an untitled frame as a source.

Seven hundred fifty peak is three times two hundred fifty

The U.S. line is 250 watts nominal and up to 750 peak, assisting to 20 mph. Seven hundred fifty divided by 250 is 3. Canada’s peak, in the same Electrek sentence, is 500. Seven hundred fifty minus 500 is 250. Other markets are held at 250 watts and 25 km/h. Twenty-five divided by 1.609 is 15.5 mph, which is the pair they print. Thirty-two divided by 1.609 is 19.9, and they print 20 mph. Neither Electrek nor the September story prints a throttle. A pedal-assist ceiling of 20 mph is the shape of a Class 1. “Up to 750 watts” of peak is not the same words as “less than 750,” which is the federal bicycle line. This desk will not award the class. The motor page is why a peak is not the nominal. The class chart is the 20 mph line they are aiming at, region by region.

Two hundred thirteen thousand dollars is on the campaign. Sixty-seven backers times $349 is not that number.

The campaign total on the page was $213,026. The $349 reward block showed 67 backers and “33 left of 100.” Sixty-seven times 349 is $23,383. That is not $213,026. Two hundred thirteen thousand twenty-six divided by 349 is 610, and only if every dollar was a $349 pledge, which the $479 bundle already contradicts. Do not turn the reward counter into the campaign, or the campaign into a count of bikes. Thirty-five newton-meters, IP65, and a 12-month warranty remain the 30 September claims. They are not in Toll’s piece. If a bike ships in April 2027 with a voltage and a torque on the carton, this page is the one that should swap the claim for the carton. Until then it is a pledge, a friction roller, and 4.75 watt-hours a mile on a brochure.
