The E-TWOW Booster Scooter: Top Speed and other details

By: Mike from DIYBIKING.COM

 

 

Now my first post about the E-Twow Booster was mostly me marveling just how many light-years ahead this scooter is compared to the heavy, slow and bulky electric scooter I owned just ten years ago.

I can pretty much rest my case on the fact the airless E-Twow tires never need inflating as the only specification you need to know, but I’m sure you’re interested in other things too, like the top speed.

 

 

Due to the scooter I borrowed set to kilometers per hour, I first tried to measure speed by clocking the number of New York City blocks per-minute I would cruise when catching all the lights green. I quickly discarded the idea when the scooter would inevitably hit a red light before the minute was up.

I later added my GPS to the handlebars of the scooter to independently verify the speed (yes, you can change the speedometer on the scooter to MPH but I was too lazy to look up how to do that just yet).

When I did this on level but pothole-laden ground, I was pleased to hit 16.9 miles an hour – certainly on the mark when you consider 16.8 miles an hour is the top speed listed on the web site. By the time I had done this, I had already used the scooter to zip to a few local places and I honestly didn’t feel like I needed to go any faster. For an electric scooter that folds down smaller than my vacuum cleaner and almost as light, it’s an impressive number.

You can thank the battery – a 33v 6.5Ah powerhouse – for delivering not just a good top speed, but for the petite, 24 pound weight. That’s probably lighter than whatever carry-on bag you used on your last flight – and, when folded, a lot easier to maneuver through a crowd. The battery claims a charge time of 1.5 to 2 hours. Even though I haven’t tested that yet, the sizable charge the scooter took on the 47 minute Metro North ride from Grand Central to Stamford suggests the claim is true.

The motor is powered by pushing the thumb-operated throttle on the right while the regenerative braking is activated by an identical throttle on the left. I adore the regenerative brake and found it gave me all the stopping power I needed – but I do wish the folks who made this thing did something different with the horn.  The built-in horn sounds like a fire alarm and should penetrate the thickest of windows of New York City cars and the thickest of skulls of New York City drivers. The quibble I have with the horn is the button is on the left, which means you can’t use the regenerative brake and the horn at the same time. So if someone cuts you off just remember to use the friction brake (pushing the rear fender down onto the wheel with your foot) if you want to use the horn.

The last figure to be aware of is the folded size: 37.2” x 5.3” x 11.8” All I can really say about that is…that’s small. It’ll fit in any car trunk, in any closet, under any desk. Unlike a lot of folding bikes I’ve dealt with I would not feel the least bit embarrassed handing this over to a coat check person at the finest restaurant – it seriously doesn’t take up much more space than a large, folded umbrella.

 

 

For readers of this review still wondering if 16.8 miles an hour is fast enough, I’ll be putting the E-Twow to a few road tests to show just how blazingly fast 16.8 miles an hour can be -  I’ll also check the claimed range of 6 – 9 miles.
