Specialized Turbo Ebike Review. The huge global bicycle company Specialized invited 30 members of the media to an exclusive ride-event in San Francisco which included: breakfast, a presentation by the Specialized engineers, a talk by the Specialized founder, a ride through San Francisco on 30 Specialized Turbos, and they capped it off with a nice lunch.
Arriving at the meeting place, I noticed that the fleet of Specialized Turbo bikes were lined up on a red carpet in an impressive (and very expensive) formation. At $6000 each that is a lot of cash. This press event is way beyond what I have seen or heard of any electric bike company ever doing. Specialized is big bucks, and knows how to throw a good party.
Let’s move on to this exciting $6,000 28-MPH bike. Specialized uses a purpose built frame (read our definition). We will look at all the features to this bike in detail in this review. The key benefit to this bike is that it can achieve close to 28-MPH, while still weighing-in at a very light 47.5 pounds. Pros Cons. EMBACHER/COLLECTION. What’s in a name?
The ideas that later paved the way for the Breezer Beamer (see page 48) were introduced on a bicycle as early as 1925. The Vélastic from the Vialle brothers and their Établissements Industriels des Cycles Élastiques of France was said, as the newspaper advertisements claimed, to make cycling as comfortable as sitting in an armchair. It was even supposed to be possible to ride down a kerb without noticing the drop. Even when you strip away the usual hyperbole of advertising, the impression that remains of the Vélastic is one of comfort; after all, a considerable portion of the frame is formed by a leaf spring.There is no seat tube so the rider sits on the end of a spring with the rest of the frame aimed at torsional strenght which it achieves to a certain degree.
The seat can of course also be adjusted in height. 1925, FRAFrame: Steel varnishedBicycle gearing: 1 SpeedBrakes: Rim Rod Brake / Rim Rod BrakeTyres: 26“ Wired Tyre / 26“ Wired TyreWeight: 38,14 lbs.

For these reasons a solid understanding of the various battery types is more than a little useful. General Battery Types While there are a lot of chemical combinations that can and have been made into useful batteries, in practice there are only four rechargeable types readily available in sizes suitable for ebikes. These are Lead Acid (PbA), Nickel Metal Hydride (NiMH), Nickel Cadmium (NiCad), and Lithium-ion or Lithium Polymer. For a long time, lead acid has been the defacto standard for EV's. Nickel Cadmium was the old standard for rechargeable consumer cells in the familiar AA, C, 9V series. Nickel Metal Hydride is quite similar to Nickel Cadmium, but with a higher energy density and a safer environmental record when disposed of in landfills.
Battery Chemistries Lead Acid Lead acid batteries are the least expensive and heaviest battery option. NiMH. BATTERY PACK.
