D8veh, When my 250w motor used to be on through pedelec or throttle it used to cause more drag from 17mph onwards. It was notably easier to cycle when no throttle or pedelec was on. My theory in this is becasue the motor has not disengaged past 15mph. So not only are you pedalling with no...

Ideally two would be better than one. I use two as the axel length allows me to. I also run two anti rotation washers that come with the motor. I got mine from Catsnapper on here for £13 for the pair delivered.

Looking at the design for geared hub motors. None that are geared should offer any real noticable drag. The drag would only come from the free spinning planet gears and possibly the grease to keep them oiled / lubricated. I'd think you'd find more noticable drag from the weight than...

I got 3 months use out the pack and paralleled up with the strong packs they've performed well. Never a glitch in balancing or using them. It's only when I've started pushing them and burning up capacity they've started to collapse. Like all cells if abused. The failed cell is actually...

I have a lyen version. It will go up to 100v if I arrange the lipo pack in that way. Its a recent investment I've purchased. But pricey none the less. You can take cheaper controllers and buy better cap's / mosfets and change the resistors to allow higher voltages much more cheaply. But...

If possible fit wider tires with lower pressure. These will usually offer substantially more grip. I've not done it on my bike. However so far i've come off twice. I'm forever getting into scrapes. Must just be me. I used to drop my car tires pressures to about 10psi in ice and bad...

I also came off in the ice. Comical more than anything. It was right at the start of my journey in a busy area in Birmingham. Victoria square. I slid on top on the bike after low siding. I skidded past an old couple, a woman on her run to work and stopped by a promotional girl handing...

Hello All, I've had chance to test these right down to critical levels. Its quite apparent that the cells are no where near as well matched as the turnigy or zippy packs at similar ratings. I've been pulling 3c out of them lately and really pushing the capacity of the cells. Its finally shown...

Most bikes are around the 20kg - 25kg. The weight isn't the most important factor though on an ebike. UNLESS you are carrying it. Unpowered I'm sure you'll only be able to go slow and steady. But i'd be more interested in the balance of how the bike feels rather than a few kilo. For the...

On front forks there more essential. But again on a 250w kit on cromo forks it never caused an issue. I then had a rear motor and ran up to 1500w, again without torque arms. Again no issues. I've then ran over 2500w on the rear and it's been ok but opted for torque arms. I may have been...

A2B hybrid is looking like a bit of a bargin!

I'd try select a kit from the most local supplier if there is one near you. The kits you've suggested all come with the same / similar components and there won't be much difference. Pricing comes from the service and warranty. You shouldn't need to run torque arm's with 250w kits. But as...

Excellent link on disco brakes. Think I'll order up 4 pairs right away!

Thats all well and good hitting its highest rpm limit. But it will also be offering the least amount of torque to the rider. If you wanted it to keep going you've have to get it back down to 100 rpm to get it to really pull you along. But then I guess your cadence would slow down so your not in...

Interesting update Eddio, Would like to have a go on the Bosch unit powered bike just to see what its like. Glad there is more support for the crank driven bikes. Makes sense after all to drive through the chain. Suprised there's not more companies willing to re-cell old batteries with...

Thanks for the quick update. I always used to use Sintered on my motorbikes. They seemed to sometimes lack a bit of feel though. Might be a little different on the cable brakes. Will try some although I think I am only meant to use Organic on the disks supplied. They get Hot quick though!

The Avid BB7 seem to get very very good reviews on most review sites also. There actually easier to adjust than my Shimano M595 Brakes as you don't need an Hex Key (Alan key) to adjust the pads. The Disk pads do need quite a bit of movement to keep them working plush. I must adjust mine once...

Most controllers I've had hardly get warm at all. What controller are you using? Most standard kits will be fine even if there enclosed. I ran a 9 fet in a backpack enclosed and it was fine for over 6-8 months. Still worked when I sold it no problems. I use a 6 fet now and have pushed...

If it works and your happy with it I'd say keep it. Unless your going to buy a complete new used bike and then a kit your still going to have to spend a minimum of £500 to get it all up and running. At the moment you have a bike that works thats cost you peanuts. You really wont get much...
