I’ve had my Woosh Rambletta bike for well over a year. Here is mine.
Out the box they are perfectly fine to get you into the e-bike world.
Looking at mine you can see where I’ve upgraded parts.
I’ve now got a Brompton 50t chainset, a chainring guide, Avid BB7 front brake setup, 8spd thumb shifters, Ergon grips, suspension seat post, Schwalbe Marathon Plus tires, bar end mirror, rear rack bag, SRAM chain, Shimano bottom bracket, new rear cassette, new rear v-brake and pads/cables, new gear cable.
A lot of the upgraded parts replaced cheapish Chinese components(common to most sub-£2k e-bikes) which although they work fine, upgrading them makes for a nicer ride as they’re better quality, the only more advanced upgrade I did was to the handlebar pivot that I found wobbled from day 1 due to poor manufacturing tolerances/quality. I squared up and flattened the contact points, then reamed and fitted a new hardened pivot pin so it’s perfect now. I’m a precision engineer btw, this is what I do!
Reliably has been 100%, I get around 35 miles before the 11.6AH battery is down to 1 bar.
The best way to ride the Rambletta is to keep it in level 1 assist and use the throttle to add exactly the right amount of assist you need for the speed you’re doing.
Otherwise you will end up riding at set speeds due to how the 5 levels of assist are limited to set mph.
I’d happily recommend the Rambletta, out the box it’s great and Woosh are very good with their customer service/after sales.
Hope that helps.
