    New Project: Orbit Orion Hybrid/Shimano Alfine 11-Speed Hub Gear/EBC 500W FWD Kit

    Not an option, I'm afraid. The fork will only allow a 160mm rotor maximum. Besides which, I'd need to gain the best part of a centimetre. There really isn't enough room to play with. I've ordered some forks and I have some Deore brakes to fit along with some larger pads. Those should do the...

    New Project: Orbit Orion Hybrid/Shimano Alfine 11-Speed Hub Gear/EBC 500W FWD Kit

    Next update: The kit arrived as promised yesterday. However, it contained the standard PAS, not the Kunteng one, as requested. There was also no speed sensor. Disappointing. Also, it seems as if the battery arrived fully charged. Either that or it's faulty. The green light stayed on when I...

    New Project: Orbit Orion Hybrid/Shimano Alfine 11-Speed Hub Gear/EBC 500W FWD Kit

    Suppliers, eh?! EBC offers a 24-hour courier service. That means I should have had delivery today. I phoned to check and it seems that won't happen. They're expecting a delivery of batteries. Now, things happen and plans go awry, but the sign of a very good company is one that lets you know...

    New Project: Orbit Orion Hybrid/Shimano Alfine 11-Speed Hub Gear/EBC 500W FWD Kit

    Trex was right when s/he said I would soon be looking for a new project after completing my Ridgeback 250W conversion! I've had the Orbit for quite a while now and it fits like a glove. It's had a SRAM Spectro S7 hub gear, but last year I converted it to a 27-speed derailleur system. Knee...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    (Yet) another update: I'm getting my hands on a Shimano Alfine 11-speed hub at the weekend at a knockdown price. All I need to do is to buy the shifter and I'm sorted. The question is do I put it on the Ridgeback or save it for the better Orbit bike? I'm leaning towards the latter option, but it...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    I checked the Wattmeter today and found there is quite a significant boost when I apply full throttle compared to the level 5 assist mode. It's nice to know I have that option, as I can use it on hills or other harder stretches.

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    Well, the bike is doing a great job on the commute. Averaging 16+MPH on an 8-mile ride. Quicker than the car. Since fitting the PAS it's worked fine. One thing I have noticed is that when I use the full thumb throttle in addition to assist level 5, it appears to give an additional boost. This...

    RWD Kit with >7-speed Freewheel

    Having successfully converted my Ridgebak hybrid to ebike status, I'm looking to convert my Orbit which is a superior machine. I'd like to go for a RWD kit so I can keep the dynohub front wheel. Problem is that the kits I've seen only offer a 6- or 7-speed freewheel gearing option. Ideally I'd...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    Right, I fitted the Kunteng sensor (actually it has no branding so I hope that's correct) very easily today. It fits into the Shimano pattern BB cup's splines very neatly. It may need a dab of glue to hold it in place, but I'll keep an eye on that. It's a much less conspicuous bit of kit than...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    The winter tyres will probably come off this weekend, depending on the long range forecast. I haven't had them on long enough to judge, but they do make quite a clatter as the studs hit the ground! Someone else I spoke to who has them said they were also useful on leaf mould on cyclepaths. My...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    It goes on the non-drive side and looks to push-fit onto the square taper axle. That means that there's no need to interfere with the BB cup.

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    Luckily, my BB axle is rather longer than necessary, so the all-in-one unit should fit. It's a bit wider than the other sensor, so it's a good job the axle is long. It'll need a retune of the display, apparently, but no big deal...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    Thanks for that. EBC have sent me a Kunteng all-in-one sensor to fit. I've got the day off tomorrow to get it fitted and try out. Hopefully that will make the two-part sensor redundant.

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    More observations: Now I'm used to the SRAM Automatix hub, I think it works really well on an ebike. The lower gear is great for quick starts on full throttle with a 38t/18t combination. Spinning out at 21MPH is fine. Where it shows a weakness is on hills. You have to stop pedalling for a brief...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    Thanks footpump. I've contacted EBC to see if it's suitable for my build. Whilst I like the throttle, I prefer the pedal assist mode. Tomorrow's task is to put the wiring somewhere much less water prone so I can use it in most weathers. Given the forecast, I'm also going to fit the Schwalbe...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    EBC do 500W kits and offer a conversion service, I think. I'm fairly sure you can tinker with the Karoo's LCD display to increase the maximum speed over the legal 25KPH limit. On my Woosh this was the work of a few seconds.

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    I don't think so. The front wheel would need to be changed and the controls might be different. In any case, I quite like adding my own effort to my rides, and I find 250W powerful enough. A 500W motor would add speed, but then you have to look at whether the brakes, etc. are capable of safely...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    Thanks! It was relatively easy and would have been even easier if I had used one of EBC's new kits. The major complication was my choice to use another battery with different connectors. With a new kit out of the box, it would have been very straightforward. Have a look at the EBC YouTube clips...

    Electric Bike Conversions FWD 250W/Ridgeback Hybrid

    After today's commute, I'm very happy with the combination so far. I averaged 16.6MPH over 8.1 miles, which is what I was getting on the Woosh when I was fitter. The Woosh would allow me to go faster on the flat because of the gearing, but I'm able to cruise along at about 20MPH on the flat on...
