"Swytch Bike sells a DIY e-bike conversion kit complete with motorized wheel and battery pack. The startup can barely keep them in stock."
"All in all, you can get going in under an hour. It’s well priced, especially compared to a new electric bike, and if you already own a good bike it means you don’t have to find the storage space for a second bike just for commuting."
"When looking into other ebike conversion kits, remember that none offer the same quality and customer support Swytch does"
"Swytch Bike is at its second evolution of their electric bike conversion kit. It is the solution to switch from a traditional bike to an electric, cheap and ecological version. It is difficult to do better."
"I think this might be one of the coolest bits of tech I've reviewed all year. The concept of converting a standard bicycle into an ebike is nothing new, but British firm Swytch has taken the concept and pretty much turned it into a work of art."
"If you have a bike you love but you want the boost of a motor to help you on your way, DIY e-bike kits might help."
"Swytch is about as effective a performer and as good value as you can get....there are no real downsides and a lot of pluses."
"Weighing in at just 1.5 pounds...Swytch Kit makes it easy to convert any bike into an eBike."
"New, lighter version of the Swytch battery and mount make this already great e-bike conversion kit even better"
"The bottom line is that once converted, it's just a really good eBike. I've ridden a lot of eBikes at this point and the Swytch kit is my favourite."
"I was already a big fan of the small format battery, but the company has now taken its handlebar-mounted Power Packs to the next level with a totally new battery design"
"Swytch Technology’s Handlebar-Bag Battery Reduced To iPhone-Size To Convert Any Bike Into Electric Bike"
"Swytch’s new conversion kit includes a 700g, smartphone-sized battery that will electrify any bike"
