Cheap Chinese bikes rust. Chain, pedals, seatpost, bolts and nuts, brakes cables and brakes. Also, most of us are overweight. We need some suspension and hydraulic brakes.

unfortunately, most of the important progress is only for cars and trucks' batteries: rapid cost reduction, durability, fast charging, standardised connectivity and energy density. e-bike batteries are left in a mixed bag with tool batteries. Just look at how little you'd pay for a car that can...

it's 40.8% - not 4%. Renewables contribute about 40% of our electricity (cheapest), 18% come from nuclear (eye wateringly expensive) and 40% from fossil fuels.

blame the journalists. The Shengshin batteries have 4C maximum charging capability, that's about 10 times what can be found on e-bikes. We charge our batteries at 0.2C and up to 0.4C. By depositing the anode maeterials with nanometers precision, CATL managed to reduce swelling when Lithium...

the number of cycles exceed 5000 in new generation batteries so using them to reduce the cost of kwh makes sense. It's a shame that progress in new batteries don't spread yet to e-bikes. However, when solid state batteries become mainstream in the next 2-3 years, we'll see them in e-bikes. CATL...

yes.

Iirc, the bizango has the chainstays flare out quite close to the bottom bracket. It may cause problems for middle motors.

For tour weight, bike and trail rides, I suggest the Tongsheng Tsdz8. It's been covered here extensively.

How hilly is your area and how heavy are you?

Tongsheng does not make hydraulic brake sensors, that's the problem. I will have to buy them in and throw away the sensored levers.

For front wheel option, I have the motor with 75mm dropout but not in 406 rim. You would have to lace the wheel. That's why Andy suggests the DWG2NC kit. 14T to 11T gives about 21% more gear inches. I thought that for folders, the cost of upgrading freewheel to cassette is justified when you...

we have front, rear (in 135mm drop out) and middle motors for your little folder. I have asked Andy to get in touch.

I can see your point. I don't like us to be involved with more items to support especially when they are not made by Tongsheng or Bafang. Will ask Andy what he wants to do.

Hydraulic brake sensors for tsdz are available but not from tongsheng. Just ask Andy. I buy stuff only from factories.

I might have what you need. Will check for you Monday.

Did you ask him?

the motor is only slightly weaker, 18A instead of 20A but the grip is better because it's the rear wheel so you get practically the same push.

if it's just the throttle issue, Andy can reprogram the throttle on the Santana3 with the Big Bear code so that it behaves exactly the same way.

No. It has a programmable throttle though.
