The Sur-Ron Light Bee is the most heavily supported machine in the catalogue: 252 parts are listed as compatible with it, spread across 16 categories. 217 of those carry a USD price. This is what those numbers look like when you line them up.
All figures are listed prices from the e-moto.bike catalogue on 21 August 2026. Compatibility is taken from what each retailer states, not from testing — always confirm fitment on the retailer's own page before ordering, because several listings carry conditions such as fitting only certain fork brands.
The shape of the catalogue
Across those 217 priced parts the cheapest is $2 and the dearest is $3,070. The median is $59. Added together the whole set comes to roughly $29,500, which is a useful reminder that a parts catalogue is a menu, not a shopping list.
The median matters more than the total. Over half of everything that fits a Light Bee is under $60, which is why the bike has the reputation it does: most of what you might want to change is inexpensive.
The cheapest option in every category
One listing per category, the lowest-priced part that fits a Light Bee:
$2 rear wheel — replacement spokes
$5 accessory — grip glue
$6 drivetrain — replacement tensioner block
$10 frame — front racing plate
$10 headlight — stock replacement headlight
$13 handlebar — MX grips
$14 brake — caliper adapter spacer kit
$17 rear suspension — shock cover
$20 display — diagnostic and programming dongle
$28 chain — drive chain
$36 seat — seat cushion
$56 fork — replacement front axle
$59 carbon — control decorative cover
$65 tire — replacement supermoto rear tire
$1,124 controller — race controller kit
$1,250 motor — race motor kit
Where the money actually goes
Add every one of those cheapest options together and the total is about $2,715 across 16 categories. Now remove the last two lines. The other fourteen categories combined come to roughly $341.
That is the single most useful number in this article. Motor and controller account for around 87% of the cheapest-possible spend across all sixteen categories. Every consumable, every cosmetic part, every bracket and cable and grip on the entire bike costs less than a third of what one race controller does.
The practical consequence is that a build budget is really two decisions. Are you replacing the motor and controller, or not? Everything else is rounding error by comparison, and you can change your mind about it cheaply.
A note on the cheapest option
Listing the lowest price in each category is a way of showing the floor, not a recommendation. In the categories where the spread is narrow — grips, drivetrain, frame hardware — the gap between the floor and something better is often ten or twenty dollars, and it is usually worth paying. The floor is most informative in the expensive categories, where it tells you the minimum cost of entry.
