I have the e-bike tuning kit for my Bosch Performance CX motor but i’ve not bothered to fit it yet, before i got the bike i thought that Yeah!, fit the kit and go ride but i’m unsure now – after having the bike for a month i’m quite happy with it as it is, obviously the increased speed will reduce the distance i can travel due to using more battery power and i kinda like the ability to do decent distances/ride all day at the moment.
Everything arrived in perfect condition with minimal assembly. It took a moment to figure out where the headlight goes, and the rear reflector has a bike-seat (not a frame) mount, but I didn't even need the instructions. (Good thing, because the "instructions" suck. Find a video instead.) That said, if you buy this, pay attention: as others have noted, the front disc brake will be on your LEFT side when you're done (the fork is reversed for packaging purposes).
Weight isn’t anything like a critical as one would assume. Weight distribution however is a different matter and this is where geometry, specifically the ratio of the front centre measurement to the chain stay length really comes into play. Battery placement is important too, and smaller batteries give an edge in the handling stakes while robbing the bike of range.
My first instinct is that it's a horrible idea. We're cyclists because we are fit enough. We've earned our way to the top. Why should some couch surfer be able to meet me there to enjoy the downhill? (I'd beat him down of course because my bike is lighter and more nimble.) And also, where do you draw the line between an electric bike and an electric motorcycle? I'd hate to meet a Zero FX or MX coming up the downhill trail I'm riding.
It is not a off-road motorbike with an electric engine and a throttle. Electric mountain bikes have motors that only work when you’re pedalling. The motor tops-up your pedalling input. It’s called ‘pedal assist’. There are differing levels of assistance (called things like ‘eco’ and ‘turbo’) that you select via a handlebar-mounted control unit. The motor also cuts out once you reach 25km/ph (or faster). There are strict limits on the power of electric mountain bikes; 250w is the maximum nominal power. More powerful than that and the bike requires tax and insurance (like a car/motorbike) and is also not allowed on bridleways at all.
Had my first crash on this bike. Right at the 500 mile mark mid-November. Sand had blown all over the bike path and I took it too fast. The bike did ok, but when I picked it back up the motor wouldn't work. I pedaled the rest of my commute and got a ride home. I suspected (and was correct) that the left brake lever was bent and the motor was not able to engage because it thought I was braking. I was nervous muscling it back, but it wasn't bent too bad. So that's what I did. And I also took the time to replace both wheels, inner-tubes, and give the bike a cleaning. The front wheel was still ok on tread but the back wheel tread was completely gone. Changing the front wheel was easy. The back wheel was more challenging because the motor cables and disc brakes. Ended up leaving the wheel on the bike and just moving it slightly to get the tube and wheel in place. Ended up just being more annoying than difficult. The chain cleaned up nice with some Simple Green. I haven't ridden on the commute nearly as much with me feeling a little more cautious and it getting dark so early (I don't need to wipe out in the bike lane into traffic...) All is well though. Have had zero issues with the motor since bending the brake back to its (or close to its) rightful position.
It is a nice bike for the money, it has some nice features. However the instructions did not fit the bike model. The given web sites noted in the instructions did not work. Went online and had to visit several other sites to get the instructions for this bike. No one site fit the bike. Very fustrating. It would be nice if the throttle also worked with the other modes. Seat is very uncomfortable. I will change that. Bike was not well packaged. I was glad to see bike was not damaged in shipment.
A few days after receiving the bike I received an email from Homdox asking if everything arrived ok and how the bike was working out. I let them know about the broken handle on the gear shift and sent them pictures. They replied on the first business day that followed stating they'd send a replacement. So... impressions right now are good. Hopefully the part arrives quickly and is in fact the right part.
It was easy, good tools were shipped with the bike. The instructions are nearly useless, though. Like other reviews state, the front fork is backwards in the picture and shipped backwards. The disk brake should be on the port/left side. Flip the handlebar clasp around and leave the dirt guard facing forward. All the cables should flow naturally this way. Pedals were ok to put on, one of the pedals took a minute to get threaded but eventually got tightened.
