Display lcd characters disappeared for a while after bike parked in rain a few times. Water seems to get in somewhere, maybe between buttons & surround where light shows or seam around the fascia. Still works, just press on, press again for light on, press + button n times for level and go...

Red! :cool: £4495

Clean, tidy look to that bike with in frame cabling. Bamboo is a nice touch, comfier for passenger "backie". Hope rain doesn't soak into the grain, esp thru those recessed bolt holes. Tho it is "more water resistant most hardwoods", even used for frame tubes. Clever that opening the top of the...

Nestling brand 7x Cree something from Amazon. Bright enough on half power for picking my way against cars headlights on highway with 4x18650 battery (full, half & flash modes). Does me for a week of goin into village & back but haven't timed it. Only gives 1min warning of low batt tho, hence...

Penetrating fluid and reasonable heat to free it. Local Bike Shop put white lithium grease on mine but prob coz its cheap and close to hand. It goes yellow with age so wipe off any excess. But wth, Copaslip or as above any grease thats ok with alloy and the paint will do. A little Vaseline goes...

Frey 1000 5, with 48v 20ah battery should roll a good long way in style. :cool:

As well as the esteemed commercial contributors to this site, here are a few more to consider, if available this side of the pond. https://electrek.co/2019/12/23/every-electric-bicycle-reviewed-2019/ As always everything depends on the budget, there are even electric moped equivalents ;-)...

A powered single wheel electric pusher trailer might be useful, as it could be attached to whatever bike one happened to be using at the time. But would the push destabilize the rider depending on pivot position? This one has a vertical pivot (vs a ball joint) behind the rear wheel for keeping...

Now that tank must be over the 250w limit, and where are the pedals? Are those lights legal, and is there still a loophole for throttles and tracked vehicles? Have you got a licence for that 100mm and can you lock it in a cabinet every night? No number plates or rubber pads either ;-) Cheers. Mikel

Adela Chen of Keyde replied thus: "B160 is built into 10Ah 30V battery ,controller and sensor inside all inside. It can work with wireless display and App, IOS and Android can both download App on our website . The B160 motor also can work without wireless display and App. The price of B160...

Keyde inform me that the wonderfully polite and helpful Sky Zhang has left the company and I'm sure we would all wish her the best. From: Sales@keyde.com "Dear respect client， Please... We apologize for any inconvenience.. In the future, Adela Chen in cc will responsible for the related work...

Nice! I do have a weakness for step-thru folders. Got the pluses of disc brakes, in-frame battery, wiring thru frame, front sus, etc. That hinge latch looks familiar and the handlepost too, folding on the outside. Is it too cramped to fold it between the frame halves then? If I'm not being too...

I suppose lengthening all the cables to a controller heated & therefore dried junction box/bag under the saddle might limit one's design options unduly. And how then to disconnect the motor for wheel removal? Y, Choices and decisions. Like the Rambla, v.clean looking & neat to take wiring thru...

"Remove battery thru the headtube" really or are you having us on? ;) Would've thought it was more practical to have the downtube join in front of the BB, instead of butting, and slide battery out the bottom. Or put it in an oversized seattube and/or seatpost tube. V.neat though ("don't mention...

Thx all, for the info. Not such a big plus for electric bikes then, at least not for me. I get out on the highway and its full on until i get to the other end, fingers crossed :). Oh, forgot hills, drat :-(. Cars, buses, vans, in a city however, different story, though gears could help instead...

Yes Yes, it seems hard on a chemical battery to be shunting it on/off like that (as i, hopefully humbly, opined in the post about Wisper 806 speed limit 'surging' issue). And i expect the variation of phases turning on/off is smoothed by the ouput capacitors charging/discharging.

Its all beyond my pay grade, but the idea of just switching in extra cells intrigued me. One vid shows a mock up of a kick scooter and they were removing & adding individual cells while it was running! So I wondered if it was some kind of matrix switching rather than just into series.

do you mean one can work out what the total losses are by multiplying the loss per FET by the number of cells to arrive at 10-20%? I.e. 6, 9, 12 vs 50 or more?

I was wondering if they were looking for beta testers, but as they're in Helsinki, Finland, I think they'd want people nearer home!;)
