New Swytch is a lot easier to install. They now have Brompton specific fittings

CosFlow Effect hey! Swytch allows me to adjust acceleration and max speed in two separate settings. This allows me to have a slow acceleration and max top speed. The Zehus rolls this into one setting. So you can only have slow acceleration and low max speed or fast acceleration and high max speed. It does have cadence level detection. But it's only useful in low power assist level where there is a range of acceleration. At the max power assist, even pedaling slow will just launch you. The zehus max speed cut off is what e-riders call going off a cliff. The sudden motor cut and rolling resistance feels like someone hit the brakes. Swytch doesn't have this problem because you can set the cut speed to the max level the motor can support you. Swytch requires adjusting the PAS (pressing buttons) to meet the same affect of cadence detection. Have you tried reducing the current down to 7A? It gives a more natural acceleration and longer ride.

@@DrJamesT I have not tried lowering the current, but I did reduce the PAS level amount. Default is 1-9. I switched it to 1-5. I feel like this gives me better range of control on how much assist I want. I've also adjusted the time the motor kicks in as per acceleration. It still kind of jolts forward, but gives me a longer period of slow movement before kicks in. Will the Driiven allow for speed beyond 15mph? How's the battery life and consumption on various speeds?

There is a hack that lets you repair a tire without removing the wheel. Removing the motor wheel is the same as a normal wheel. This motor has no wires. Check out @3:14 for motor resistance test, while I was riding on down tower bridge. Riding flats is like riding up tower bridge.

which kit did you buy?

ascensionyze X yes to single speed version because you’ll be replacing the wheel and hub. Driiven has its own titanium triangle so you just need to buy a steel brompton, titanium fork, titanium Driiven.

DrJames I have the 2009 titanium w/ all the bells and whistles. Including the light. And 6 speeds. Will I loose all these features if I add the Zehus ? How to order this in USA ? Who will know how to install it? Is this the best option? Is the new Switch a better option?

It's via bluetooth, same process as pairing with a bluetooth headphone. If you can't get it to work, it sounds like a call to tech support is required.

Yes you can

Are you saying I can use 2nd, 3rd or 6th gear on the rear wheel?

John Kang custom powder coat glossy grey done by a specialist in hackney london cost £300

Used Brompton £500 + £300 new paint job and tune up + £1200 for motor and titanium triangle at the time of review. Check the website for latest prices. These come from Italy so it might be cheaper for you EU folks.

@@DrJamesT thanks for your information......Top job

I don't recommend friction based dynamo kits for this system because you are using electricity to turn your lights on via friction, which is wasted as heat. Rechargable led lights is direct electricity to light.

Sordini Orlando this kit is for the rich folks. Keep using your legs your heart will thank you

DrJames _ He might be Rich, How much?

Each carrier limits by number of Amp Hours of the battery. So I wouldn't use the word never you just need to find the carrier that accepts it

1st of all, great video! Yours is probably the only one that puts a practical test over this misterious electric kit. To answer your question - I'd love to see your review on Vello+. Personally I ride Vello Urbano v1.0 basically everyday and I love it! I rode once Vello+ while I was living in london (bikefix has it) and I was amazed. Comparing any bike+ to Gocycle would be even more awesome!

So is Zehus the best option for adding Brompton ekit? Or is there better option out there? Thanks.

@@NewWorldDAO It's the most expensive option. Swytch is the budget option to consider. Check Nano (UK) and Grin Tech (Americas) has been around for 10 years.

the battery is inside the motor hub itself - you have to send it back to get it replaced.

@@DrJamesT Wow! that seems like a very interesting design - thanks for the response.

It looks better. Your brompton bike won't have a battery on the frame. It's lighter.

A 2 speed shift from the factory 6 speed version is possible. The Bike+ version can be charged by cycling it -> crazy workout. I agree in 3-5 years time the mileage might decrease to impractical levels. The company apparently will service it at a cost. It should cost no more than a third of the motor price. This is why the zehus kit is recommended for the rich folks. It's the best in terms of design but like a super car, the price is for people with a practical mindset. If you want a budget kit get the Swytch kit. If you want something in between or beyond check out the Grin Tech series. If you live in the UK and have the cycle to work scheme at your company go for the official brompton.

Try using another phone or call Zehus

It does not. But you'll need to tweak it. It works with both iphone and android. You can get an android phone for £20-£40

Peter Simonson you set it once and that’s all you need. The rest is to monitor the motor. The electric bike itself can run out electricity. Risks is the same. Bring a spare power bank.

solid points

what do you mean by back up?
