I recently came across that Triumph is now into the electric bicycle marketplace with their first ever (and only) offering as the 'Trekker'.
It's basically a Triumph designed and manufactured frame with almost all Shimano electric drive and mechanical components.
The motor puts out a typical 250 Nm of torque that is adequate for most street needs and the battery is also adequate and sized appropriately at 500 Wh. Other goodies such as a display for range and lights for night riding are also part of the deal.
There is a review here that states that the range is about 90 miles, which is probably more than enough for the majority of riders :
Another review found that its underpowered, heavy, and expensive for the cost :
As does this one :
Whereas this review was less critical showing how using gears and speeds can get the most out of this bike :
With other reviews still in the dark :
"Automotive brands are also getting in on the action: BMW is making electric bikes and motorcycles, Audi is manufacturing electric mountain bikes, Ford recently acquired e-scooter startup Spin, and Jeep recently unveiled a high-powered electric mountain bike."
So there is likely to be more to come from other car and motorcycle companies.
