Alex, ' just a few trolls' you said. If you want respect and careful consideration for your products, join the forum properly, participate, contribute like subscribe as a trade member or better still, advertise to help with funding. How many real questions have you answered? You and KatLee...

If you want to ride unassisted, you'd need a frame that is rigid but still has a bit of flex. Too rigid, it'll sap your energy, flex in wrong places, even worse. That's why Bromptons are so well liked. They atre strong and flex in the right places. I converted my cheap Brompton B75 and take it...

The topic is how to market a new product in the Internet age. Here is a new company with products that look much like others. How will it create a good image? The problem they have here is they rely on people without technical skills to answer technical questions. The specific issue with their...

let's take an example so the numbers will help you make sense. Your bike has 26" wheels, a 44T chainring, 8-speed and you fit a 36V BBS01 motor. You climb a hill on maximum throttle at 70rpm and your motor produces 80NM at the chainring. 70RPM is the rotational speed = 70/60 * 2 * PI radians/s =...

so you know it well. How does yours compare?

it's loosely based on current political personae. Nicol Trowbridge is BJ. Would he desparately need his own war so he can play Churchill?

Did you ask if your company can offer you another scheme? Halfords? Evans? Vivup? Cycleplus? Caboodle? Green Commute Initiative? etc. Hatti here could not work with cyclescheme.co.uk - the contract went back and forth with them for years.

That's good. 20" it is then. I would suggest you take a look at my 20" folding e-bike, the Woosh Rambletta. It's good for commuting and easy foresty trails. https://wooshbikes.co.uk/?rambetta

No, it's not correct. The torque on a crank drive is measured at the chainring. For the same torque, you need the same power at the motor. The principle is called conservation of energy.The different arrangement of cogs in the gearbox does not change that. The 40:1 is the overall ratio of...

what kind of car?

I like the look of the CYC Photon. Who doesn't like ISIS bottom bracket instead of a square taper bottom bracket? Also, the chainring and clutch look very well machined, waterproofing also looks very good. The only criticism I have of the CYC Photon is there is not yet YT video of a complete...

The Hamax clamp has long bolts. It can accommodate slightly wider tubes.

wires? they have been channelled years ago. The clamp can deal with slightly wider tubes.

are you talking about the clamp for the Hamax child seat that goes on the seat post? If you are, it took me 10 minutes to fit the Hamax seat on the Santana.

I have now watched your video of you climbing up that hill, and I am pretty confident that you can do that very easily with an XF07 kit. It would be a straightforward installation with left side pedal sensor. I have one XF07 in 20" rim if you are interested.

BAFANG | M-Series (bafang-e.com) Bafang's M series are quite expensive to buy, not much difference in price compared to Shimano motors.

they are, the charger's 42V limit for 36V battery is well proven for decades. However, when the batteries age, that limit must be lowered. The problem is the output voltage is set in the vast majority of chargers by a potentiometer instead of digitally set. There is no way you can program the...

it's a relative risk. Over time, components age and degrade, especially paper capacitors. 5 years is a good compromise. Batteries are at their most vulnerable to fire risks when 100% full, a situation that is common at the end of the charging process. People tend to forget that they have left...

1 Volt * 1 Amp = 1 Watt 1 Volt * 1 Amp * 1 Hour = 1 WH (spell: one watt hour) Your bike runs on 36 Volts (average), your battery is rated like this: 36 Volt * 5.5 Amp * Hour = 198 WH (Watt Hours) A new 36V 15AH battery gives you 540WH, roughly 3 times the range of your old battery. A new 36V...

Did anyone watch netflix 'the diplomat'?
