Re: E-Bikes (electric bicycle) : A comprehensive guide Just thought I'd share some quick notes of using a Swytch Bike conversion kit to add electric pedal assist to my wife's hybrid city bike.
For context her grandparents have been early adopters of the earliest iteration of the Swytch conversion kit for their Bromptons. They live at the bottom of a hill and while very agile for octogenarians, they needed some help to get them over said hill. That's where the kit comes in. In essence it comes in 3 main parts (I'm a petrol head married into a cycling family so I'm still learning - forgive any incorrect terminology): - A new front wheel with the motor built in to the hub of it
- A magnetic disc to put around the hub of the pedals with attached sensor to link to the motor
- And a battery pack (of varying sizes) and mounting bracket
Having moved from the flatter part of the Pennines to hilly Leeds, some help was needed with the commute to work for my wife. Thought I'd get her the Swytch kit. They had a pre-order system where they sell and deliver the kits in tranches. We got the extended range (30 km) pack vs the standard 15 km one, worked out to about £380ish all inclusive (basically what we liked is that it seemed a well regarded and reasonably priced way to electrify an existing bike compared to getting a bespoke e-bike). Took about 5-6 weeks to arrive. All we had to do was make sure we provided the exact front rim size as they clearly make the wheels to order.
Delivery by UPS was a bloody nightmare, we kept checking the website and sod's law, the one day neither of us was WFH, UPS just drop off the kit at a neighbours where we had to wait a few days to collect from as they were then away for the weekend as well. Annoyingly I think UPS must've handled it incorrectly because the rim was ever so slightly warped (we found out when we took it to a bike shop when the front brake kept catching at one point slightly).
Assembly using the provided instructions and kit was a bit of a faff - it wasn't quite as easy as the video makes it appear. A lot of the cabling and sensors etc are held to the frame with zip ties. Also we found it odd that the components came screwed together, so we had to unscrew them to attach and then screw them in, but that was probably just our frustration making sense of it all.
All that being said, it's been a few weeks and a few rides to work, weather permitting, and touchwood, my wife's found it's really making a difference getting up the big hill just in the centre of town. We're still likely to take it to a bike shop again to double check about the front wheel and contact Swytch in case it becomes a larger issue. Here's a photo post assembly. Shiny new front rim, with hub motor and the big chunky battery pack on the front handle bars - they sell other products too that allow you to mount the battery pack elsewhere. One side effect of the big mounting bracket was needing to find a new mounting point for the front reflector. Also any phone mount would have to go on the stem. Thinking of getting a Loop Micro Mount
